Abstract: A method and apparatus to control frequency deviation of a portable transceiver (PT) (122) utilizing a time-division-duplex (TDD) protocol for communicating with a base transceiver (116). The base transceiver (116) transmits (708) a first signal having first deviation levels (706). The PT (122) receives (802) the first signal, measures (808, 810, 824) it to derive estimates of the first deviation levels, and stores (826) the estimates in a memory (322). The PT (122) generates (828) a second signal having second deviation levels (830) controlled by control signal values (323), samples (832) the second signal to derive a second received signal, and appraises (902) the second received signal to derive estimates of the second deviation levels (830). The PT (122) compares (906) corresponding estimates of the first and second frequency deviation levels (830) to derive adjusted control signal values (908) for controlling the second deviation levels (830) to approximate the first deviation levels (706), and thereafter controls (914) the second deviation levels (830) in accordance with the adjusted control signal values (908).

Abstract: A transceiver (125) for receiving messages and transmitting acknowledgments includes a receiver (365) for receiving a message and time information indicative of a first time slot, a display (400) coupled to the receiver (365) for presenting the message, and a monitor element (430) coupled to the display (400) for determining, at occurrence of the first time slot, whether the message has been presented. A transmitter (380) coupled to the monitor element (430) and the receiver (365) transmits, in response to occurrence of the first time slot, a message acknowledgment when the message has not been presented. When the message has been previously presented, a read acknowledgment, rather than the message acknowledgment, is transmitted to indicate both message reception and message presentation.

Abstract: Blind access (100, 300, 400) to a desired encryption key of a predetermined first goup member is provided to a second group. The first group encrypts a plurality of first group member encryption keys using a predetermined algorithm and transfers to the second group, the encrypted plurality of first group member encryption keys with corresponding unencrypted first group member identification fields, IDs, and a list of IDs corresponding to the first group members. The desired ID-free encryption key is selected and encrypted by the second group using a predetermined algorithm. The doubly encrypted key is transferred to the first group, decrypted by the first group and transferred to the second group for decryption. Thus, the encryption key is provided without knowledge to the first group of which member's encryption key is being examined and with knowledge to the second group of only the desired encryption key.

Abstract: A floating point conversion circuit (10) converts a fixed point data signal having a fixed point data format (200) to a floating point data signal having a floating point data format (300). The floating point conversion circuit (10) contains a twos complement circuit (110) and a programmable logic array (120) which determines the magnitude of the fixed point data signal and produces an exponent signal and a shift signal based on the magnitude determined. The floating point conversion circuit (10) also contains a barrel shifter (130) which shifts the fixed point data signal to adjust the magnitude based on the shift signal and thus produces a signal. The floating point conversion circuit (10) outputs a floating point data signal having a floating point exponent portion (320) represented by the exponent signal and a floating point portion (330) represented by the signal.

Abstract: The current invention is a method (100), super-regenerative transceiver (300), and computer system (500) for providing short range communication with reduced current drain (102). A control unit (306) provides an amplifier "ON" pulse (314) periodically to a radio frequency amplifier (302) to allow reduced current drain. The radio frequency amplifier (302) eliminates antenna effects in an input signal signal (308) to provide an amplified input signal (316). The control unit (306) also provides a receiver "ON" pulse (320) to a super-regenerative receiver (304) immediately following the amplifier "ON" pulse to allow reduced current drain. The super-regenerative receiver (304) detects received data given the amplified input signal.

Abstract: A battery (200) includes a device (201) used for simulating a high temperature condition of a thermistor (216) located in battery (200). The battery (200) includes a charging node (203), temperature node (205) and ground node (207). A control circuit (209) is used with lithium ion cell (211) to measure voltage of lithium ion cell (211). Control circuit (209) produces a control signal when a desired voltage is reached during recharging. The control signal works with a high voltage switch (217), thermistor (216), diode (213) and resistor (215) to control the voltage on temperature node (205). Any change in voltage on temperature node (205) may then be detected by an attached charging system to allow it to change its mode of operation.
