Patent number: 5889737Abstract: A portable electronic device (10) comprises a radio circuit (150) contained in a housing (152) having positive (156) and negative (158) contacts electrically coupled to the radio circuit (150). A substantially flat, elongated, flexible battery cell, forming a compliant energy storage device (32), provides a single, continuous wrist band (30) and has positive (160) and negative (162) terminals. A latch mechanism (176) releasably secures the housing (152) to the wrist band (30) between opposite ends (172, 174) of the wrist band (30), and permits the contacts (156, 158) of the housing (152) to align with and abut the respective terminals (160, 162) of the wrist band (30) while the wrist band (30) is worn on the user's wrist. Multiple housings (152, 180) may be stacked to add electrical functions.Type: GrantFiled: October 31, 1996Date of Patent: March 30, 1999Assignee: Motorola, Inc.Inventors: Rachid M. Alameh, Francis P.

Patent number: 5815820Abstract: A portable radiotelephone (200) adjusts its transmit power responsive to the position of a movable antenna (213). The antenna (213) is movable between a retracted (313) and an extended position (314). The portable radiotelephone (200) transmits at low power when the antenna (213) is retracted and at high power when the antenna (213) is extended. Additionally, the portable radiotelephone (200) can notify a remote base station of the change in transmit power at any time during transmission.Type: GrantFiled: May 11, 1992Date of Patent: September 29, 1998Assignee: Motorola, Inc.Inventors: Joshua P.

Patent number: 5815807Abstract: A disposable portable radiotelephone subscriber unit (101) comprises a power supply (255), a transceiver (205, 207) and a controller (215). The power supply (255) has stored therein a predetermined measure of power capacity (281). The transceiver (205, 207) is permitted to operate for a predetermined period of time (405) responsive to the predetermined measure of the power capacity (281). The controller (215) monitors a rate of depletion of the predetermined measure of the power capacity (281). The controller (215) permits operation of the transceiver (205, 207) when the power capacity (281) is being depleted at a desirable rate, thereby decreasing the predetermined period of time (405) that the transceiver (205, 207) is permitted to operate. The controller (215) prevents operation of the transceiver (205, 207) when the power capacity (281) is being depleted at an undesirable rate, thereby prolonging the predetermined period of time (405) that the transceiver (205, 207) is permitted to operate.Type: GrantFiled: January 31, 1996Date of Patent: September 29, 1998Assignee: Motorola, Inc.Inventors: Rashid Masood Osmani, Michael P.

Patent number: 5497382Abstract: The extended error correction process of the present invention error corrects a data message that has been transmitted a plurality of times. The process first receives the data message at least twice, logically combining the first and second messages received to form an error indication word. The error indication word is then used to locate the error locations in each message after which some of the errors are complemented, depending on the total number of errors found. The message is then decoded and used for transmit power changes, channel reassignment, to release a call, etc.Type: GrantFiled: June 10, 1994Date of Patent: March 5, 1996Assignee: Motorola, Inc.Inventors: Stephen N. Levine, Michael P. Metroka

Patent number: 5463646Abstract: The process of the present invention error corrects sub-audible data words that have been transmitted over a voice channel. A data word may be transmitted up to three times if an acknowledge is not received by the transmitter. If any of the three possible repeats of the received data word are decodable, an acknowledgment is transmitted. If all three repeats of the data word contain uncorrectable errors, a bitwise majority vote is performed on the three data words. If the result of the majority vote is decodable, an acknowledgement is transmitted to the sender.Type: GrantFiled: January 7, 1993Date of Patent: October 31, 1995Assignee: Motorola, Inc.Inventors: Thomas M. Dillon, Robert K. Krolopp, Michael P. Metroka

Patent number: 5148471Abstract: A portable radiotelephone with an integral voice recognition circuit is disclosed. Control of the voice recognition circuit is achieved with a foldable housing element which, in a closed position, covers an external keypad and control buttons. When the foldable housing element is in an open position, the portable radiotelephone is placed in an off-hook condition, the voice recognition circuit is activated, and the acoustic transducers are coupled to the voice recognition circuit. When the foldable element is in a closed position, the portable radiotelephone is placed in an on-hook condition, the voice recognition circuit is deactivated, and the electroacoustic transducers are coupled to the radiotelephone. A rapid closing and opening of the foldable element results in the voice recognition circuit being deactivated while the portable radiotelephone remains in the off-hook condition.Type: GrantFiled: November 20, 1989Date of Patent: September 15, 1992Assignee: Motorola, Inc.Inventors: Michael P.

Patent number: 5117449Abstract: Both paging and cellular radiotelephone functions can be combined in a small, lightweight, single device by sharing most circuitry. The apparatus can receive paging signals simultaneously with radiotelephone signals because of dual receivers (105 and 110). When the paged party receives a page, an alert tone, a vibration, a visual indication, or a voice message is used to alert the party. Information extracted from the paging signal can be stored in memory (101) for later use. The paged party can select among messages stored in memory. If a message contains a telephone number, the paged party can call that number using the radiotelephone function at the touch of a button. The apparatus's keypad (102) can be used to program the paging function receiving frequency, identification code and type of paging system.Type: GrantFiled: April 8, 1991Date of Patent: May 26, 1992Assignee: Motorola, Inc.Inventors: Michael P. Metroka, Stephen V. Cahill

Patent number: 5107487Abstract: The power control apparatus of the present invention is comprised of a local oscillator signal path coupled to a mixer (106) through a variable attenuator (107) and an IF signal path coupled to the mixer (106) through two variable attenuators (108 and 109) coupled in series. The IF signal path attenuators (108 and 109) are controlled by digital control circuitry (111) while the local oscillator path attenuator (107) is controlled by the control circuitry through a level shifter (110). The power level of the signal generated by the mixing of these two signals is less than the conducted output of the radiotelephone's power amplifier.Type: GrantFiled: May 28, 1991Date of Patent: April 21, 1992Assignee: Motorola, Inc.Inventors: Richard J. Vilmur, Michael P. Metroka

Patent number: 5045824Abstract: A ceramic filter mountable on a multi-layer circuit board. The filter contains a two-level mounting surface for matingly engaging with a circuit board. One surface portion of the two-level mounting surface extends through a recessed area formed upon a surface of the circuit board. By mounting the filter such that the mounting surface matingly engages with the recessed area of the circuit board, the heightwise requirement of the filter above the surface of the circuit board is reduced.Type: GrantFiled: September 4, 1990Date of Patent: September 3, 1991Assignee: Motorola, Inc.Inventor: Michael P.

Patent number: 5036532Abstract: A unique cellular portable telephone (100) automatically accommodates a power source change during a cellular telephone call between the portable's battery (300) and another battery or an external power source from vehicular adaptor (200), such as, for example, a battery eliminator adaptor, a hands-free adaptor, or a mobile transceiver adaptor. The operating mode of portable telephone (100) also automatically changes when it is coupled to or decoupled from vehicular adaptor (200) during a cellular telephone call. For example, when vehicular adaptor (200) is plugged into portable telephone (100), the portable display (116) is not disabled when inactive for a predetermined time.Type: GrantFiled: December 27, 1990Date of Patent: July 30, 1991Assignee: Motorola, Inc.Inventors: Michael P. Metroka, Thomas J. Walczak, Robert K. Krolopp
