Patent number: 11734407Abstract: Methods, systems and devices for generating an authentication key are provided. Two or more communications devices can generate an authentication key by monitoring a physical stimulus that is experienced by both devices (e.g., a common physical stimulus). Each device can then use an identical, predetermined algorithm to generate a common authentication key based on the stimulus. The devices can use the common authentication key to establish a secure network.Type: GrantFiled: June 10, 2022Date of Patent: August 22, 2023Assignee: Apple Inc.Inventors: David C. Andrus, Philip F.

Patent number: 6807437Abstract: An apparatus and system for providing wireless communication for a portable computer system. In one embodiment, the present invention is a wireless communication apparatus. The wireless communication apparatus is adapted to be communicatively coupled to a portable computer system. In the present embodiment, the apparatus is comprised of a PCB (printed circuit board). It is noted that the PCB of the present invention is separate from and in addition to the PCB of the portable computer system to which it is coupled. The apparatus is further comprised of an antenna, coupled to the PCB adapted to transceive a specific radio frequency band. The apparatus is further comprised of a passive radiator coupled to the PCB. The passive radiator is adapted to provide an omindirectional radiation pattern for the wireless communication apparatus.Type: GrantFiled: January 31, 2001Date of Patent: October 19, 2004Assignee: 3com CorporationInventors: David C.

Patent number: 6314128Abstract: Synchronized receiver circuitry and methods are provided for a spread-spectrum communications system which includes a transmitter for generating a data-modulated carrier signal encoded with a predetermined discrete-stepped, cyclical pseudo-random noise code sequence, and a receiver for despreading and demodulating the encoded spread-spectrum modulated carrier signal. The receiver has a pseudo-random noise code generator, a mixer connected to the pseudo-random noise code generator for mixing the encoded spread-spectrum modulated carrier signal with the code sequence provided by the pseudo/random noise code generator to despread the carrier signal, and an indicator in the receiver for generating a received signal strength indicator analog signal. The synchronized receiver includes a clock which provides a frequency output corresponding to the frequency of the clock driving the pseudo-random noise code generator in the transmitter.Type: GrantFiled: July 17, 1998Date of Patent: November 6, 2001Assignee: World Wireless Communications, Inc.Inventors: Philip A.

Patent number: 4794622Abstract: An improved miniature hand-held low power transmitter utilizing a surface acoustic wave (SAW) resonator as the control element to establish the carrier frequency of the oscillator. The SAW resonator stabilizes the frequency of the transmitter to within 0.05% of the center frequency of the SAW resonator for the condition of the user's hand enclosing the transmitter. This stability allows the companion receiver to operate at a narrow bandwidth, 0.1% of the center frequency of the SAW resonator, thus reducing the spurious noise received by the receiver. The configuration of the transmitter allows schemes such as pulse position or pulse width modulation to be utilized to encode the transmitted information. The physical size of the SAW resonator allows the transmitter to be mounted within a housing small enough to be enclosed by the user's hand.Type: GrantFiled: May 19, 1988Date of Patent: December 27, 1988Assignee: Linear CorporationInventors: Marvin Isaacman, David C.
