Patent number: 10383112Abstract: Wireless client devices within a wireless network exchange data with other wireless devices during particular time slots determined by the network. More particularly, the system generates and wirelessly broadcasts synchronization information to the client devices, where the synchronization information contains individual masks to be applied to bit fields of individual client devices, where said time slots are determined in accordance with the masked bit fields. In such a manner, client devices can be coordinated to communicate with the system in a dynamic real-time tiered manner.Type: GrantFiled: January 11, 2016Date of Patent: August 13, 2019Assignee: Proxense, LLCInventors: David L. Brown, Fred S. Hirt

Patent number: 10374795Abstract: A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.Type: GrantFiled: December 31, 2015Date of Patent: August 6, 2019Assignee: Proxense, LLCInventors: John J Giobbi, David L Brown, Fred S Hirt

Publication number: 20170085564Abstract: A system and method provide efficient, secure and highly reliable authentication for transaction processing and/or access control applications in which only biometric input is required from the user. A Personal Digital Key stores a biometric profile that comprises a representation of physical or behavioral characteristics that are uniquely associated with an individual that owns and carries the PDK. The PDK wirelessly transmits the biometric profile over a secure wireless transaction to a Reader for use in a biometric authentication process. The Reader compares the received biometric profile to a biometric input acquired at the point of transaction in order to determine if the transaction should be authorized.Type: ApplicationFiled: November 29, 2016Publication date: March 23, 2017Inventors: John J Giobbi, David L Brown, Fred S Hirt

Publication number: 20160133123Abstract: A system and method provides efficient and highly reliable customer and asset tracking. A Personal Digital Key (PDK) is associated with and carried by a user or fixed to an asset. The PDK wirelessly communicates with a receiver/decoder circuit (RDC) that can be coupled to a variety of electronic devices. The RDC authenticates the PDK based on received data and stores information to track customers and provide improved service. The RDC can be coupled to or integrated with a variety of electronic devices. The operation of the electronic device is determined based on an identification code of the detected PDK and an identification code of the RDC. The electronic device, the PDK or both can be configured with a personalized user interface and execute specific functions based on stored state information associated with the PDK and RDC identification codes.Type: ApplicationFiled: January 14, 2016Publication date: May 12, 2016Inventors: John J.

Patent number: 9113464Abstract: In a wireless network, a cell's transmission power and reception sensitivity may be dynamically adjusted along with those of a client device detected in the cell. Thus, in other words, when a client device is in proximity of a particular reader device, the transmission power levels and reception sensitivities of the reader device and the client device may be adjusted in an effort to require the client device to be “drawn in” towards the reader device to conduct a data transaction between the reader device and the client device.Type: GrantFiled: January 5, 2007Date of Patent: August 18, 2015Assignee: Proxense, LLCInventors: Fred S.

Patent number: 8750710Abstract: An example method includes receiving radio frequency (RF) signals from a cable modem termination system (CMTS) in a small form factor pluggable optical transmitter; converting the RF signals to optical signals in the small form factor pluggable optical transmitter; and transmitting, by the small form factor pluggable optical transmitter, the optical signals on a network. More specific embodiments can include RF signals that are modulated, where a modulation error ratio (MER) of the RF signal varies substantially linearly with Carrier to Composite Noise (CCN), and the converting is implemented by a laser transmitter. Other, more specific, embodiments include routing the RF signals through a pre-distortion RF amplifier RF variable attenuator, and coupling the optical transmitter to a chassis of the CMTS.Type: GrantFiled: July 15, 2011Date of Patent: June 10, 2014Assignee: Cisco Technology, Inc.Inventors: Fred S.

Patent number: 8467676Abstract: A multi-wavelength optical transmission system includes a plurality of primary optical transmitters, each being configured to provide directly modulated analog optical signals at non-uniformly spaced apart wavelengths. An optical multiplexer having a plurality of optical input ports receives the analog optical signals from each of the plurality of primary optical transmitters and provides a wavelength division multiplexed signal over an optical fiber coupled at an output thereof. A spare optical transmitter is coupled to an input port of the optical multiplexer and, in response to detecting failure of a failed one of the plurality of primary optical transmitters, is tuned to provide a directly modulated analog optical signal at a spare wavelength that is selected as to be non-uniformly spaced relative to at least some of the non-uniformly spaced apart wavelengths according to tuning data.Type: GrantFiled: January 16, 2009Date of Patent: June 18, 2013Assignee: Cisco Technology, Inc.Inventors: Fernando Xavier Villarruel, Kuang-Yi Wu, Fred S.
