Patent number: 5751322Abstract: In an ink-delivery system of an ink-jet printer, the needle of the interface mechanism is fully recessed into a cavity of a needle-holding structure and the septum seals the end of a hollow tower. The connection between the needle and a septum tower allows for transportation of ink from an ink reservoir to an ink-jet pen in the printhead. The tower is configured to be inserted into the cavity so that the needle pierces the septum. To prevent needle pricks and cuts, the cavity has an aperture with a diameter less than that of a human finger. Therefore, the narrow diameter aperture prevents inadvertent digital access to the needle. Furthermore, the septum tower may be attached to a replaceable component, such as an ink reservoir or a pen. Each time that a component is replaced, the relative positioning of its septum tower may change. A floating-bushing assembly loosely retains the needle-holding structure so that the structure has limited freedom to move.Type: GrantFiled: February 13, 1996Date of Patent: May 12, 1998Assignee: Hewlett-Packard CompanyInventors: Gary L. Miller, Kenneth R. Williams

Patent number: 5634045Abstract: Referring to FIGS. 1 and 2, I/O control modules (IOCMs 25-29) have channels which communicate by way of timer buses (71, 72) and pin/status buses (75-77). Channels (86, 87) are partitioned by each timer bus (71, 72) into separate blocks of channels (86, 87) which are provided with access to different timebase values from timebase channels (80, 81) by their respective timer bus (71, 72), so there is no loss of resolution because each channel in a timer bus block (e.g. 86) can concurrently receive the same timebase value from its corresponding timer bus (71). Pin/status buses (75-77) allow simultaneity of control among the channels (e.g. 58) coupled to the same pin/status bus (e.g. 76). Pin/status buses (75-77) and timer buses (71, 72) can be independently partitioned.Type: GrantFiled: November 13, 1995Date of Patent: May 27, 1997Assignee: Motorola, Inc.Inventors: Vernon B. Goler, Gary L. Miller, David Rivera

Patent number: 5631853Abstract: Referring to FIGS. 2, 13, and 14, the tag value transferred by timebase select signals (50) indicates which timebase is presently available on timer bus (71). In one embodiment, each channel (61, 62, 80, 81, and 86) compares the tag value of the timebase select signals (50) with a user programmed tag value stored in a register portion (264). If the stored tag value matches the tag value being driven on the timebase select signals (50), then the match signal (263) is asserted to indicate that the channel is either to provide a timebase value to the timer bus (71) for timebase channels (80, 81), or to receive the timebase value from the timer bus (71) for work and other channels (86). FIG. 15 illustrates examples of how timebase values (namely TB1-TB8) may be selectively provided during the different time slots of a timer bus (e.g. 71).Type: GrantFiled: November 13, 1995Date of Patent: May 20, 1997Assignee: Motorola Inc.Inventors: Gary L.

Patent number: 5506910Abstract: An automatic equalizer sequentially adds subdued narrow band audio reference signals of different frequencies to an audio program signal being broadcast, and measures the magnitude of each successive broadcast reference signal to determine a measured frequency response of an audio amplification system and its environment. The gains, or attenuations, of various frequency bands in the broadcast signal are adjusted as needed to produce a desired frequency response. In one embodiment the added reference signals are masked by adding the reference signals only when the test frequency is adjacent to a relatively large magnitude frequency component of the program signal. Additional masking is performed by the reference signal being relative quiet and of a short duration such as two to twenty cycles. A narrow band notch filter operates in synchronism with the reference signal adder to eliminate any program signal component at the frequency of each reference signal being added.Type: GrantFiled: January 13, 1994Date of Patent: April 9, 1996Assignee: Sabine Musical Manufacturing Company, Inc.Inventors: Gary L.

Patent number: 5218235Abstract: Power stealing circuit receives data signals on its signal input terminal and diverts some power from the signal input terminal to its power output terminal to power another circuit. When the voltage on the signal input terminal exceeds the voltage on the power output terminal, positive supply power is "stolen" from the signal input terminal to the power output terminal. When the signal input terminal is below the power output terminal, the two terminals are disconnected. A similar circuit "steals" negative supply power. In some embodiments, a comparator compares the voltages on the two terminals and regulates the power stealing operation.Type: GrantFiled: January 4, 1991Date of Patent: June 8, 1993Assignee: Catalyst SemiconductorInventors: Christopher H. Patterson, Gary L. Miller, Jeffrey A. Berkman

Patent number: 5174216Abstract: A digital sound reproducing system which produces a plurality of sound effects from digital data stored at predetermined addresses in a digital sound memory. A controller connected to the digital sound memory causes recall of a sound data from a predetermined sequence of addresses when triggered. This recalled sound data is converted into an analog audio signal for reproduction by a speaker. In a first embodiment the digital sound reproducing system is disposed in the car of a model train. Magnets disposed between the tracks trigger corresponding sound effects when the digital sound reproducing system detects passage of the magnets. A speed sensor detects the rotation rate of a wheel of the car to permit sound effects to be synchronous with the rate of speed of the model train. The digital sound reproducing system may alternately be disposed in a fixed structure and triggered by a command signal or by detection of passage of the model train.Type: GrantFiled: March 13, 1991Date of Patent: December 29, 1992Assignee: Miller ElectronicsInventors: Gary L.

Patent number: 5129078Abstract: A system comprises a service processor and a plurality of operating units dependent on the service processor. The service processor responds to service requests from the operating units and services the operating units one at a time. A scheduler is responsible for assigning priority to the operating units and determining the order in which the service requests are handled. A register contains a value indicative of the operating unit currently being serviced and is under control of the scheduler. According to one aspect of the present invention the register is also under control of the service processor itself. Another register, under control of the service processor, is coupled to the scheduler to generate service requests thereto independent of the operating units. A memory addressable by the service processor stores data. The service processor is capable of generating addresses for the memory derived from the contents of the register indicative of the operating unit currently being serviced.Type: GrantFiled: August 19, 1988Date of Patent: July 7, 1992Inventors: Stanley E.

Patent number: 5117498Abstract: A data processor in which return from subroutine execution is not dependent on the presence of a particular instruction at the end of the sequence of instructions comprising the subroutine. The disclosed embodiment comprises a micro-programmable processor designed for servicing a timer subsystem. The return from subroutine apparatus comprises a decrementor which may be enabled to decrement once for each instruction executed by the processor and a return address register. A jump to subroutine instruction loads a return address into the return address register, enables the decrementor and loads the program counter with the address of the first instruction of the subroutine. When the decremento reaches a count of zero, the return address is loaded into the program counter. Provision is also made for using the same hardward to execute a single instruction a predetermined number of times before proceeding to the next instruction.Type: GrantFiled: September 19, 1990Date of Patent: May 26, 1992Assignee: Motorola, Inc.Inventors: Gary L. Miller, James C. Nash

Patent number: 5042005Abstract: A timer subsystem which provides a data processor servicing the timer subsystem with the ability to inhibit the match recognition logic of the timer subsystem while the processor is servicing the subsystem. The disclosed embodiment comprises a sixteen-channel timer subsystem with a dedicated service processor. The service processor, under control of the micro-coded programs executing thereon, is capable of disabling a match recognition latch in the timer channel currently being serviced. This feature provides the ability to prevent unwanted matches which occur while the service processor is updating the match register, for instance. Another feature of the timer subsystem is the inhibition of multiple matches to a single match register value by disabling the match recognition latch upon the occurrence of a match and re-enabling it only when the match register is written by the data processor.Type: GrantFiled: August 19, 1988Date of Patent: August 20, 1991Assignees: Motorola, Inc., Delco Electronics Corp.Inventors: Gary L.

Patent number: 4811191Abstract: Disclosed is a rectifier circuit which utilizes field effect transistors, and which includes current sensing resistors to adjust the drive to the field effect transistors to avoid forward biasing the intrinsic bipolar transistor in the field effect transistors to thereby avoid injecting current into the substrate where the field effect transistors are formed on a common substrate. In addition, the current sensing resistors provide a fast startup, which is achieved both in the case where the field effect transistors are formed on a common substrate as well as those implementations where the field effect transistors do not share a common substrate. Current limiting resistors are also included to prevent overloading the field effect transistors and injecting current into the substrate when the field effect transistors share a common substrate.Type: GrantFiled: March 28, 1988Date of Patent: March 7, 1989Assignee: Catalyst Semiconductor, Inc.Inventor: Gary L.

Patent number: 4800365Abstract: A CMOS digital-to-analog converter includes a modified R-2R resistive ladder network connected to 16 pairs of bit switches responsive to the various digital inputs to produce an internal analog voltage representative of the digital input. Each pair of bit switches includes an N-channel MOSFET and a P-channel MOSFET. The on resistance of the P-channel MOSFET is adjusted to precisely match that of the N-channel MOSFET by driving the gate of each P-channel MOSFET with the output of a CMOS inverter referenced between V.sub.CC and a reference voltage that is adjusted to cause the on resistances of a P-channel "monitor" MOSFET and an N-channel "monitor" MOSFET to be equal. A reference voltage is generated by a circuit that generates a temperature-invariant source current from a V.sub.BE difference between first and second transistors, causes part of it to flow through first, second, and third resistors, the third resistor having a voltage across it established by the V.sub.Type: GrantFiled: June 15, 1987Date of Patent: January 24, 1989Assignee: Burr-Brown CorporationInventors: Robert L.
