Publication number: 20240098449Abstract: A wireless proximity detection system employs short-range wireless communication to detect the proximity of a user device within a strictly defined wireless zone and as a result trigger a desired action. The proximity detection system may utilize one or more leaky feeders to define the wireless zone and the associated received signal strength(s) detected by the user's wireless device. Alternatively, a compact planar antenna structure coupled with a highly shielded radio transceiver is used to allow a similar precise low-power radio beam to be emitted defining a small location to enable identification of a wireless device such as a smartphone in a given area in front of the device. The planar antenna structure allows a compact and low-cost fabrication method and the use of common printed circuit fabrication methods provide an integrated solution.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Applicant: Simpello LLCInventors: William Benjamin Robertson, Roger Mabillard, Jean-Samuel Chenard, Xavier Bernard, Craig A.

Patent number: 8824568Abstract: For use as or in connection with a set-top box, a digital TV broadcast signal is decoded by processing its audio stream into and read from a FIFO buffer. According to certain embodiments, fullness of the FIFO buffer is compared to a reference fullness, which can be updated based on changes to the bit rate of the audio stream. In response to the FIFO buffer fullness, the set top box regulates the rate at which the audio stream is decoded. The disclosed decoding methods do not need to rely on the accuracy or presence of a system time encoded into the broadcast signal.Type: GrantFiled: January 26, 2009Date of Patent: September 2, 2014Assignee: Entropic Communications, Inc.Inventor: Pierre Roger Bernard Le Pifre

Patent number: 7351353Abstract: The invention is directed to a method and composition for providing roughened copper surfaces suitable for subsequent multilayer lamination. A smooth copper surface is contacted with an adhesion promoting composition under conditions effective to provide a roughened copper surface, the adhesion promoting composition consisting essentially of an oxidizer, a pH adjuster, a topography modifier, and a uniformity enhancer. A coating promoter may be used in place of the uniformity enhancer or in addition to the uniformity enhancer. The adhesion promoting composition does not require a surfactant. The process may further comprise the step of contacting the uniform roughened copper surface with a post-dip, wherein the post-dip comprises an azole or silane compound or a combination of said azole and said silane. The post-dip may further comprise, alone or in combination, a titanate, zirconate, and an aluminate. The pH adjuster is preferably sulfuric acid and the oxidizer is preferably hydrogen peroxide.Type: GrantFiled: January 7, 2000Date of Patent: April 1, 2008Assignee: Electrochemicals, Inc.Inventors: Roger Bernards, Hector Gonzalez, Al Kucera, Mike Schanhaar
