Abstract: A document is operatively coupled to a printing device, either directly or through a network such as the Internet. A print schedule is stored that keeps track of when a document should be printed on the printing device. When the print schedule indicates the document should be printed, the document is automatically transmitted to the printing device without user intervention. The printing device automatically prints the document, again without user intervention. The document can be stored on a electronic device, such as a personal computer connected to the printing device, or can be stored on a document server accessible to the printing device through the Internet. A user profile is stored that contains information about the recipient of the document, such as name, email address, household income, and interests. This user profile is updated when a document is printed on the printing device.

Abstract: A docking station for a portable computer contains a platform and a movable guide bar connected to the docking station and extending over the platform. The guide bar is capable of guiding the portable computer into proper alignment with the docking station when the portable computer is placed on the guide bar and pressed downwardly into the platform. The guide bar may contain a thermally conductive guide protrusion capable of mating with a heat sink on the portable computer. Heat is transferred from the heat sink on the portable computer to the guide protrusion on the guide bar. The guide bar itself may also be thermally conductive, providing a further avenue for heat to be transferred from the portable computer to the docking station.

Abstract: A pressure sensitive electronic device has a display, a case, a processor, and a pressure sensor, such as one or more force sensitive resistors. When the pressure sensor detects pressure on the case, the information displayed on the display is changed. Pressure in one or more dimensions (X, Y, and/or Z) on the case is detected by the pressure sensor. Most commonly, the information that is changed on the display is the repositioning of a cursor on the display, although switching between various operating modes and/or writing on the device can also be performed. The cursor is repositioned corresponding to the direction and magnitude of the pressure detected on the case. Pressure can also be used to execute an operation corresponding to the position of the cursor on the display. Keys or other input devices (mouse, trackball, etc) are not required to control the movement of the cursor on the display, execute operations, or switch between various operating modes of the device.

Abstract: A method and apparatus for detecting the end of life of a print cartridge for a thermal ink jet printer determines the status of the print cartridge and warns the user if the print cartridge is at or near the end of its useful life. In a first mode of operation, an initial temperature of a printhead contained in the print cartridge is checked after a threshold amount of ink is expelled from the printhead, such as for a high density print swath or during a service routine. This initial temperature is then compared with a maximum initial temperature. If the initial temperature exceeds the maximum initial temperature, a warning about the status of the print cartridge is sent to a user. If the initial temperature does not exceed the maximum initial temperature, the user is informed of the remaining life portion of the print cartridge. In a second mode of operation, a final temperature is checked after a period of time elapses since the threshold amount of ink is expelled from the printhead.

Abstract: An input device, such as a mouse, has a base unit movable in an x direction and a y direction. Inside this base unit is a position detection mechanism which detects movement of the base unit. A handle is attached to the top of the base unit. The handle has sufficient length and width to accommodate the fingers of a human hand curled about it, and has an adjustable length, width, and orientation. After adjustment and during normal operation, the handle does not move in any direction independent of movement of the base unit. The handle has one or more switches on it. Each of the switches is positioned for activation by a different finger of a human hand curled about it.

Abstract: A docking station for a first portable computer and also for a second portable computer, where second portable computer is wider than the first portable computer. The docking station has a base plate and a width variation guide pair, which is compressible to accommodate the width of the second portable computer. The guide pair is not compressible to accommodate the width of the first portable computer.

Abstract: A method and apparatus for determining an optimum print density for an ink jet printer uses characteristics of a printer and its peripheral components such as an ink jet printhead, and an ink supply unit to reach an optimum print density. The ink jet printer receives a print command from a computer. The printer reads an ink drop volume parameter from a printhead memory device on the ink jet printhead and stores this parameter in a printer memory device on the ink jet printer. The processor in the printer determines an ink density compensation value for the ink jet printhead based on the ink drop volume parameter. The processor on the ink jet printer applies the ink density compensation value to the print command, thereby creating a depleted print command. Finally, the depleted print command is printed.

Abstract: A portable electronic device has an outer shell, a first speaker assembly, and a second speaker assembly. The first speaker assembly has a first speaker, a first speaker chamber, and an outer edge. The second speaker assembly has a second speaker, a second speaker chamber, and an outer edge. The first and second speaker assemblies are capable of being in a normal position, where the first speaker assembly outer edge and the second speaker assembly outer edge are substantially flush with the outer shell of said portable electronic device. The first and second speaker assemblies are also capable of being in an extended position, where the first speaker assembly outer edge and the second speaker assembly outer edge extend beyond the outer shell of the portable electronic device. Preferably, the first and second speaker chambers each have a larger volume when the first and second speaker assemblies are in the extended position than when they are in the normal position.

Abstract: A battery, usable with one or more battery support units and/or electronic devices, contains a memory which contains a mailbox. The battery receives a request from a battery support unit or an electronic device to write error data in the mailbox. In response to this request, the battery stores the error data in the mailbox. The battery then receives a request from a battery support unit or electronic device to read the error data from the mailbox. In response to this request, the battery transmits the error data to the battery support unit or electronic device that requested it.

Abstract: A portable computer includes a base with a keyboard on an upper surface and having a front portion and a rear portion. A display housing is connected to the base. There is a palm rest disposed and extending across the front portion of the base. The palm rest includes a numeric keypad. The numeric keypad can be enabled by depressing a function key located on the keyboard, such as the Num Lock key, or optionally by a switch associated with a cover. This cover can also be used without an associated switch to prevent accidental activation of a key on the numeric keypad.

Abstract: A battery support unit, such as a defibrillator battery charger, tests a battery having a memory for an error condition. If the battery support unit finds an error condition with the battery, it transmits error data to a mailbox located in the battery's memory. Other battery support units or electronic devices, or even this battery support unit at a later date, can read the error data in the mailbox and take an appropriate action. For example, the battery support unit can read the mailbox and, if it finds error data placed there by itself, another battery support unit, or an electronic device, enable an indicator, such as an indicator that informs a user that maintenance needs to be performed on the battery. When battery maintenance has been selected, the battery support unit reconditions the battery by charging and discharging the battery a predetermined number of times, and also performs additional testing on the battery.

Abstract: A controller drives a fan's motor to proportionally control fan speed based on changes in heat output from electrical components in a local environment. The controller is connected to a temperature sensor and the fan motor. The temperature sensor senses local environment temperature, while exhibiting a lag time. The controller provides closed loop control and implements a system pole which cancels out the temperature sensor lag time during steady state operations. The controller implements an integration of a difference between sensed temperature and a reference temperature to generate the system pole.

Abstract: An information retrieval device displays portions of a dynamically modifiable document requested by a user. The information retrieval device has a controller connected to a display screen, input selector switches, such as buttons, and memory, such as non-volatile flash memory. One or more documents, such as a newspaper or magazine, is stored in the memory. A receiver, such as a pager, modem, or FM radio receiver, is connected to and dynamically updates the memory. When the device is turned on, a first portion of a document is displayed on a display screen. When the user wants to see a different portion of the document, or a different document altogether, she presses one of the buttons. Upon detection that a button was enabled, an action is performed that changes the display on the display screen.

Abstract: A signature card is used with a computing system. The card plugs into a host computer and is, for example, a personal computer memory card internal association (PCMCIA) card. The card includes a write-on pad for receiving input from a stylus. A memory stores the input received by the write-on pad. An interface transfers the input stored by the memory to the host computer. The card also includes an independent power source which is independent from the host computer.

Abstract: A heat conductive substrate is mounted within a through-opening of a printed circuit board. An integrated circuit then is mounted to one side of the heat conductive substrate, while a heat sink is fixed in thermal contact to the other side of the substrate. There is no direct thermal contact between the IC and the PC board. The heat conductive substrate is mounted to the PC board by applying a controlled pressure to normal surfaces of multiple portions of the substrate. Such pressure reducing the thickness and expands the area of the pressed portions locking the substrate to the PC board. An air gap occurs between the substrate and the PC board everywhere except for the pressed regions of the substrate. Such pressed regions occur along the periphery of the substrate.
