Filed:

Sep 2, 2008

Appl. No.:

12/202736

Inventors:

Jaime Tseng - Saratoga CA, US
Peter Jie Guan - Fremont CA, US
Li Ma - San Jose CA, US

Assignee:

Linear Technology Corporation - Milpitas CA

International Classification:

H01M 10/46

US Classification:

320166

Abstract:

An oscillator that includes an energy storage system configured to store energy, a ramp circuit configured to generate an oscillating ramp signal having a slope that is a function of the amount of energy stored in the energy storage system, a charge circuit configured to controllably deliver energy into or remove energy from the energy storage system, a comparator circuit configured to compare the oscillating ramp signal with a reference signal; and/or a charge control circuit configured to cause the charge circuit to deliver energy into or remove energy from the energy storage system based on the comparison by the comparator circuit.

Appl. No.:

12/154793

Inventors:

Alan Chokov - Manasquan NJ, US

International Classification:

G06Q 40/00
G06Q 30/00

US Classification:

705 26, 705 36 R

Abstract:

The financial portal and search engine micro markets consumer specific finance inquires and needs to product specific financial service providers and then allows these service providers to display their expertise and compete on the cost of the service or product required by the consumer interactively so that the consumer is simultaneously aware of all financial providers offering the specific products or services required by the consumer and the service providers can communicate to the consumer simultaneously, the cost of such products and/or services. These services are self-managed by the service providers through their Personal Management Account on the site, which allows the provider to choose what he wants to present; in what format, duration and market exposure.

International Classification:

G06F 15/18

US Classification:

706 12

Abstract:

The present disclosure describes an extension of the Pólya Tree approach for constructing distributions on the space of probability measures. By using optional stopping and optional choice of splitting variables, the present invention gives rise to random measures that are absolutely continuous with piecewise smooth densities on partitions that can adapt to fit the data. The resulting optional Pólya tree distribution has large support in total variation topology, and yields posterior distributions that are also optional Pólya trees with computable parameter values.

Abstract:

A unified channel contention scheme is proposed such that spatial reuse can be enabled by a wireless station (STA) when a basic service set (BSS) color of a received signal cannot be resolved. If the detected frame is an intra-BSS frame, then the STA should not contend the channel for the PPDU duration. If the detected frame is an inter-BSS frame, then the STA uses OBSS Packet Detection (OBSS-PD) level as the CCA level for channel contention. Furthermore, when BSS color cannot be resolved, channel contention schemes for WiFi signal and non-WiFi signal are differentiated. If the received signal is detected as WiFi signal, then the STA uses WiFi-SIG Detection (WD) level as the CCA level for channel contention. If the received signal is detected as non-WiFi signal, then the STA uses Non-WiFi-SIG Detection (NWD) level as the CCA level for channel contention.
