Publication number: 20140185475Abstract: Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.Type: ApplicationFiled: December 20, 2013Publication date: July 3, 2014Applicant: Apple Inc.Inventors: Zhu Ji, Johnson O.

Publication number: 20140029464Abstract: Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.Type: ApplicationFiled: September 27, 2013Publication date: January 30, 2014Applicant: APPLE INC.Inventors: Johnson SEBENI, Yu-Lin WANG, Jianxiong SHI

Publication number: 20130033426Abstract: The invention provides a handheld projector and a projection method thereof. The handheld projector includes a projection module, a control module, a detecting module and a steering module. The control module drives the projection module to project an image towards an object, which includes a cursor. The detecting module generates a shift signal according to shift of the handheld projector, and transmits the shift signal to the control module. The control modules drives the steering module to rotate the projection module towards an opposite direction of the shift of the handheld projector, so as to make the image projected by the projection module stay in a fixed position of the object. Through the invention, projected image is not easily shocked, and the user only need move the handheld projector when change of the cursor position is desired, and thus operation convenience is greatly enhanced.Type: ApplicationFiled: August 2, 2012Publication date: February 7, 2013Applicants: INVENTEC APPLIANCES (PUDONG) CORPORATION, INVENTEC APPLIANCES (SHANGHAI) CO.,LTD., INVENTEC APPLIANCES CORP.Inventors: Yu-Lin Wang, Wei-Hung Chen

Patent number: 7764728Abstract: An apparatus for determining multipath correlations among a search range of input data, and a method thereof. The multipath searcher comprises a pseudo noise (PN) code generator, a correlator, and a data combiner. The PN code generator generates a first PN code corresponding to a first multipath component of the input data, postpones a first period based on the search range, then generates a second PN code corresponding to a second multipath component of the input data. The correlator is coupled to the PN code generator, and correlates the input data with the first PN code and the second PN code to produce a first correlation and a second correlation. The data combiner is coupled to the correlator, receives the first and the second correlations to determine a primary multipath component with a higher correlation thereto.Type: GrantFiled: October 18, 2006Date of Patent: July 27, 2010Assignee: Via Technologies, Inc.Inventors: Sung-Chiao Li, Huoy Bing Lim, Ching-Chia Hsu, Yu-Lin Wang

Patent number: 7643523Abstract: Aspects of the present invention are directed to the use of optical gain structures that include alternating layers of gain medium and transparent heat conductors in which the gain medium itself functions as a correction optic. The gain medium changes to an optimum or desired shape because of the thermal changes occurring as the materials of the optical gain structure(s) reach a desired optical output condition. At the desired optical output conditions, the gain medium conforms to a desired shape. The desired shape may be, for example, that of an optical surface of a transparent heat conductor. By designing the initial shape of the gain medium such that the physical contact with the transparent heat conductor is maximized at the desired optical output conditions, conductive heat transfer between the gain medium and heat conductor(s) is maximized at the desired optical output condition.Type: GrantFiled: November 21, 2007Date of Patent: January 5, 2010Assignee: Textron Systems CorporationInventors: Hsian P.

Publication number: 20050156563Abstract: An inductive charger is adapted for a portable electrical devices or information products and connects with a rectifier for charging. The inductive charger includes a hollow carrier, at least a coil surrounding an outer surface of the carrier, fixed magnets and at least a sliding magnet. The carrier has a pair of end portions opposite to each other, and the fixed magnets are respectively located on the end portions of the carrier. N poles and S poles of the fixed magnets are oriented coincident with each other. The sliding magnet is located between the fixed magnets, and N pole and S pole of the sliding magnet is opposing to N poles and S poles of the fixed magnets. When the carrier is driven, the sliding magnet moves back and forth between the fixed magnets due to magnetic repulsion of the sliding magnet, which changes flux of the coil thereby producing induced electromotive force.Type: ApplicationFiled: January 5, 2004Publication date: July 21, 2005Inventors: Heng-I Lin, Feng-Ming Chuang, Yu-Lin Wang, Wen-Yi Chu
