Patent number: 9092065Abstract: An input device has a base, two shafts, a touchpad and a switch. The shafts are pivotally connected between the base and the touchpad, and intersect each other. When the touchpad is pressed, the shafts rotate relative to the base and the touchpad simultaneously. As the shafts intersect each other, an intersection of the shafts is nearby or exactly on a center of the touchpad, such that the shafts can pull down the touchpad from the center. Thus, no matter what location on the touchpad is pressed, a pressing force is spread uniformly, which makes the touchpad move down evenly without tilting. Besides, pulling down the touchpad from the center can further prevent leverage and deformation of the touchpad, thereby avoiding affecting the user's feel of pressing. To sum up, the input device can make the touchpad move down evenly, and prevent the touchpad from deformation.Type: GrantFiled: November 28, 2013Date of Patent: July 28, 2015Assignee: ELAN MICROELECTRONICS CORPORATIONInventor: Lu-Yuan Hsueh

Patent number: 8750643Abstract: Embodiments related to the removal of blur from an image are disclosed. One disclosed embodiment provides a method of performing an iterative non-blind deconvolution of a blurred image to form an updated image. The method comprises downsampling the blurred image to form a blurred image pyramid comprising images of two or more different resolution scales, downsampling a blur kernel to form a blur kernel pyramid comprising kernels of two or more different sizes, and deconvoluting a selected image in the blurred image pyramid according to a Richardson-Lucy deconvolution process in which a bilateral range/spatial filter is employed.Type: GrantFiled: March 25, 2013Date of Patent: June 10, 2014Assignee: Microsoft CorporationInventors: Jian Sun, Heung-Yeung Shum, Lu Yuan, Long Quan

Patent number: 8571271Abstract: A dual-phase approach to red eye correction may prevent overly aggressive or overly conservative red eye reduction. The dual-phase approach may include detecting an eye portion in a digital image. Once the eye portion is detected, the dual-phase approach may include the performance of a strong red eye correction for the eye portion when the eye portion includes a strong red eye. Otherwise, the dual-phase approach may include the performance of a weak red eye correction for the eye portion when the eye portion includes a weak red eye. The weak red eye may be distinguished from the strong red eye based a redness threshold that shows the weak red eye as having less redness hue than the strong red eye.Type: GrantFiled: May 26, 2011Date of Patent: October 29, 2013Assignee: Microsoft CorporationInventors: Lu Yuan, Fang Wen, Jian Sun

Patent number: 8554011Abstract: Techniques for automatic exposure correction of images are provided. In particular, the exposure of an input image may be improved by automatically modifying a non-linear function that characterizes the luminance of shadow, mid-tone, and highlight portions of the image. The input image may be segmented into a number of regions and each region is assigned a zone, where the zone indicates a specified range of luminance values. An initial zone assigned to a region of the image may be changed in order to reflect an optimal zone of the region. Based, in part, on the optimal zones for each region of the image, luminance modification parameters may be calculated and applied to the non-linear function in order to produce a modified version of the input image that improves the appearance of overexposed and/or underexposed regions of the input image.Type: GrantFiled: June 7, 2011Date of Patent: October 8, 2013Assignee: Microsoft CorporationInventors: Lu Yuan, Jian Sun

Patent number: 8477734Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.Type: GrantFiled: March 24, 2009Date of Patent: July 2, 2013Assignee: QUALCOMM IncorporatedInventors: Sharad Deepak Sambhwani, Wei Zeng, Yibo Jiang, Lu Yuan, Mehmet Yavuz, Pavan Kumar Vitthaladevuni, Bibhu P.

Patent number: 8264975Abstract: Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. Thermal noise in a sideband may be measured and used as an estimate of thermal noise in a signal band. In one design, samples containing a desired signal centered at DC or a frequency higher than DC may be partitioned into blocks of K samples. Each block of K samples may be transformed with an FFT to obtain a corresponding block of K transform coefficients for K frequency bins. The power of transform coefficients for frequency bins in the sideband may be computed. Thermal noise may be estimated based on power values for the frequency bins in the sideband. Power values for frequency bins in the signal band may also be obtained and used to estimate total received power. RoT may then be estimated based on the estimated thermal noise and the estimated total received power.Type: GrantFiled: September 30, 2008Date of Patent: September 11, 2012Assignee: QUALCOMM IncorporatedInventors: Lu Yuan, Danlu Zhang, Mehraban Iraninejad, Sharad Sambhwani

Patent number: 8254279Abstract: Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.Type: GrantFiled: April 21, 2008Date of Patent: August 28, 2012Assignee: QUALCOMM IncorporatedInventors: Charles E.

Patent number: 8060929Abstract: There are various methods of securing programs and data on a processor. The external address enable pin of the processor is sampled upon a power-on or reset to the processor, to determine whether or not accesses to external memory are allowed. Other changes to the external address enable pin are thereafter ignored. In addition, if it is determined that an internal memory access is occurring, the contents of such an access can be masked to prevent unauthorized viewing of the memory contents via an external memory bus. In addition, a programmable security bit may be set to disable the dumping of flash memory contents, allowing only the erasing of the flash memory.Type: GrantFiled: September 21, 2009Date of Patent: November 15, 2011Assignee: Texas Instruments IncorporatedInventors: Hugo Cheung, Lu Yuan, Terence Chiu, Bolanle Oladapo Onodipe
