Patent number: 11913597Abstract: A product-display system for displaying and securing a retail product. The system may include a retainer having a retainer bracket and a retainer body coupled to the retainer bracket. A retaining cable may be coupled to the retainer body at an opening in the retainer body. A fastener that may be unfastened to release the product from the retainer may only be accessed through the opening of the retainer body such that when the retaining cable is coupled to the opening, no fasteners of the retainer may be visible or accessible. The system may also include a display stem for holding the retainer and product. The display stem may include a recess for receiving at least a portion of the retainer body. The retaining cable may extend through the display stem and may simultaneously transmit power and data to a displayed product. The retainer may be returned to and held on top of the display stem using a retaining cable.Type: GrantFiled: December 1, 2021Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Sheng Yang, Eric W.

Patent number: 8404555Abstract: A fabricating method of a semiconductor device is provided. Pillars are formed on a substrate. A first oxide layer is continuously formed on upper surfaces and side walls of the pillars by non-conformal liner atomic layer deposition. The first oxide layer continuously covers the pillars and has at least one first opening. The first oxide layer is partially removed to expose the upper surfaces of the pillars, and a first supporting element is formed on the side wall of each of the pillars. The first supporting element is located at a first height on the side wall of the corresponding pillar and surrounds the periphery of the corresponding pillar. The first supporting elements around two adjacent pillars are connected and the first supporting elements around two opposite pillars do not mutually come into contact and have a second opening therebetween.Type: GrantFiled: August 10, 2010Date of Patent: March 26, 2013Assignee: Nanya Technology CorporationInventor: Charles C.

Publication number: 20130019783Abstract: Four nylon legs were added to old Lazy Susan to allow much improved functionality of the device. Work to date demonstrates that the addition of a set of four nylon legs represents a major departure from, and adds a new dimension to, the age-old Lazy Susan. As such, this seemingly small difference between Lazy Susan and my Moby Susan may prove to be very substantial and significant. Incorporation of Moby Susan as a built-in feature in the design of future microwave ovens is suggested.Type: ApplicationFiled: July 9, 2012Publication date: January 24, 2013Inventor: Charles C. Wang

Patent number: 7142610Abstract: A turbo coded communication system includes a gray scale mapper in a transmitter for generating a symbol constellation of modulated signals points that can be separated by boundary lines in the constellation space into bitwise groups of zero bits and one bits where the shortest distance from a boundary line to received value in the constellation space indicates the bitwise soft metrics that is computed using a set of bitwise soft metric equations are a function of the minimum distance using closed form algebraic equations in turbo decoding receiver.

Patent number: 6044116Abstract: The turbo coding system combines: a) repetitive turbo encoder bit partitioning and decoder bit deletion; with b) error-floor mitigating encoder non-flushing the second constituent encoder with the second a-posteriori probability (APP) decoder starting backward recursion from any possible states as a powerful improvement to conventional turbo coding. The repetitive turbo encoding process repeats the bits of the systematic root sequence and appends flushing sequence prior to interleaving and encoding by the second constituent turbo encoder for providing an interleaved repetitive second encoded output for turbo decoding. The error-floor mitigating turbo encoding process does not flush the second constituent encoder to the zero ending state so that turbo decoding forward recursion may be end in any possible state and backward recursion may start from any possible state to avoid potential mismatches between the forward and backward recursions.Type: GrantFiled: October 29, 1998Date of Patent: March 28, 2000Assignee: The Aerospace CorporationInventor: Charles C.

Patent number: 6028897Abstract: The turbo encoding process does not flush tail bits of the second constituent encoder at the end of a block systematic data so that this second constituent encoder is not placed in a known zero ending state but placed in any possible ending state from which backward recursion starts at all possible beginning states during decoding to estimate the systematic data while avoiding potential mismatches between the forward and backward recursions during decoding, and between the systematic and second parity-check tail bits during decoding. The modified a posterior probability second decoder implements the backward recursion starting from all possible states. Significant bit error rate improvement is had without a significant error floor in the range of interest. Iterative decoding provides iterative results that are subject to majority voting selection for improved estimations of the decoded systematic data sequence.Type: GrantFiled: October 22, 1998Date of Patent: February 22, 2000Assignee: The Aerospace CorporationInventor: Charles C.

Patent number: RE42884Abstract: An nth root transformation is used for generating near Gaussian metrics from non-Gaussian metrics for input into a conventional turbo decoder that is based on the assumption that the input sequence to the decoder has a Gaussian distribution. The nth root transformation transforms channel non-Gaussian statistics to near Gaussian statistics for use with conventional turbo decoding for improved noncoherent communications over a non-Gaussian channel, such as a fading channel. For a differential coherent PSK waveform, where the channel statistics of a demodulator are non-Gaussian, for example, in the presence of fading, the nth root transformation is used to transform the non-Gaussian statistics to near Gaussian statistics for generating near Gaussian metrics, for improved PSK communications.Type: GrantFiled: October 22, 2008Date of Patent: November 1, 2011Assignee: The Aerospace CorporationInventors: Charles C.
