Patent number: 5379404Abstract: An electronic code plug programming apparatus and operating method that automatically recognizes and configures a radio frequency communication device without reference to a prestored signal in the radio frequency communication device. The programming apparatus uses a communication interface operating in either a first or second configuration using first and second signal sets, respectively. The first configuration and signal set allows communication with a non-microprocessor based radio frequency communication device while the second configuration and signal set allows communication with a microprocessor based radio frequency communication device. In response to the success or failure of a direct code plug read request communicated to an undetermined radio frequency communication device, a controller recognizes whether the device is microprocessor based without reference to a prestored signal therein and programs the device, configuring operational parameters according to its recognized capabilities.Type: GrantFiled: September 2, 1993Date of Patent: January 3, 1995Assignee: Motorola, Inc.Inventor: Gregg E. Rasor

Patent number: 5359607Abstract: A radio receiver (100) having a receiver section (103) receives and processes an information signal to provide received information having an error factor that varies at least with respect to operational parameters of the receiver section (103). In the radio receiver (100), a method is embodied for adaptively controlling the operational parameters of the receiver section (103) to optimize the error factor of the received information. The method (400, 400', 400") comprises operating in a first receiver mode in response to a predetermined mode select parameter, correlating a first signal recovered from the received information to at least a portion of a first code word to establish a first error criteria, and operating in the first receiver mode while the first error criteria does not exceed a predetermined error criteria.Type: GrantFiled: November 13, 1991Date of Patent: October 25, 1994Assignee: Motorola, Inc.Inventors: Tuan K. Nguyen, Xuan-Khanh T. Tran, Richard A. Erhart, David J. Hayes

Patent number: 5349695Abstract: A selective call receiver (100) operates to recover an information signal and is capable of receiving a battery supplying a first voltage (203) that is multiplied to generate a second voltage (212). The selective call receiver (100) includes [comprises] a processor (106) that extracts message information contained within the recovered information signal for presentation and a power-on reset circuit (112) that generates a power-on reset signal having [comprising] first and second portions corresponding with a processor reset and a processor execute state, respectively. The power-on reset signal changes from the processor reset to the processor execute state when the second voltage (212) exceeds a sum of a PMOS threshold voltage and a NMOS threshold voltage, thereby completing a power-on reset of the processor (106).Type: GrantFiled: December 3, 1992Date of Patent: September 20, 1994Assignee: Motorola, Inc.Inventors: Zhong K. Zhong, Barry W. Herold

Patent number: 5309483Abstract: A data recovery device (208) for recovering data symbols having a period T from a received data stream. The data recovery device samples at least one data symbol in the received data stream at a rate determined by an integration envelope (301) having the period T. The samples are accumulated as a weighted sample count representing a recovered data symbol that is then stored as at least one recovered data bit.Type: GrantFiled: September 16, 1991Date of Patent: May 3, 1994Assignee: Motorola, Inc.Inventors: Mark L. Oliboni, James G. Mittel, Richard A. Erhart

Patent number: 5303402Abstract: A radio receiver has a receiver section (103) that receives an information signal and an integrated circuit (105) in which a default operating condition of an electronic device is selectively programmed. A mask option programming link in the integrated circuit (105) is programmed while maintaining electrical isolation of a programming bias from the electronic device (207). The mask option programming link has a first conductor (211) in a first layer with first (212) and second (213) programming contact terminals. A second conductor (210) that determines a default operating condition of the electronic device (207), resides in a second layer that is electrically isolated from the first layer. When sufficient programming bias is applied to the programming terminals of the first conductor (211), energy dissipated by the first conductor eliminates coupling of the second conductor (210) to the electronic device (207), changing its default operating condition.Type: GrantFiled: March 9, 1992Date of Patent: April 12, 1994Assignee: Motorola, Inc.Inventors: Kevin McLaughlin, Barry Herold

Patent number: 5300937Abstract: An antenna system maximizes a gain associated an antenna loop by expanding a free end away from a fixed end of the loop in response to first and second portions of the antenna loop resiliently engaging first and second interior sides of a housing to maintain the position of the antenna loop and increase the effective area of the antenna loop.Type: GrantFiled: September 21, 1992Date of Patent: April 5, 1994Assignee: Motorola, Inc.Inventors: John K. Capp, Keith W. Neutzman, John J. Parkes, Jr.

Patent number: 5247519Abstract: A radio frequency programmable selective call receiver (100) provides a received signal having a recovered address, a command code, and a programming field. A decoder determines selection of the selective call receiver in response to correlating the recovered address (403) with a predetermined address stored in a non-volatile memory (107) that includes a plurality of registers for storing a plurality of configuration words which determine operational characteristics of the selective call receiver (100). A controller (105) selects and executes a bulk programming mode (1004) when a recovered data word (503) is unmasked, or a selective programming mode (1008, 1009, 1010, 1011, 1012) when the recovered data word (503) is masked. The bulk programming mode modifies at least one programmable option of the selective call receiver (100) by re-writing all programmable options in the range of a plurality of registers with data included in the unmasked data word.Type: GrantFiled: June 20, 1990Date of Patent: September 21, 1993Assignee: Motorola, Inc.Inventors: Gregory O. Snowden, Rick Johnson, Thomas F. Holmes, Mark T. Stair

Patent number: 5206576Abstract: A battery charger that allows insertion of a battery for charging. When the battery is inserted it mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charger. The mechanical engagement of the battery with the activation mechanism causes at least one vent in the energy source to open. The energy source generates power when the at least one activating gas infiltrates into the energy source through the at least one open vent. The power generated by the energy source is coupled to the battery for charging.Type: GrantFiled: September 13, 1991Date of Patent: April 27, 1993Assignee: Motorola, Inc.Inventor: Leon Jasinski
