Abstract: A digital measurement system and method for optical applications including a mobile client device having a digital camera and an audio port, and a laser measurement device having a laser and a magnetic card reader. The laser measurement device and the magnetic card reader are electrically connected to the audio port of the mobile client device. The mobile client device is configured to activate the laser at the same time as the digital camera is activated, capture an image of a patient, and calculate position of wear measurements based on a location of a laser mark in the captured image. The mobile client device also allows an order for a frame and lenses to be submitted to an ophthalmic laboratory, and payment transactions to be processed using the magnetic card reader.

Abstract: Methods and apparatus are described for improving receiver performance in a multicarrier communication network in which an encoded symbol is transmitted over a transmission channel in the communications system. A model of the transmission channel is estimated, said model characterising an effect of intercarrier interference on at least one carrier in the multicarrier system. The received symbol is decoded using the estimated model to remove a predicted effect of intercarrier interference. A pre-processor is also described for operation in conjunction with a communications receiver in the network. The pre-processor includes a channel estimator operable to estimate at least one feature of the communication channel based on a received signal. The pre-processor modifies the received signal dependent on the at least one estimated feature and provides the modified signal to the communications receiver.

Abstract: A write-back coherency data cache for temporarily holding cache lines. Upon receiving a processor request for data, a determination is made from a coherency directory whether a copy of the data is cached in a write-back cache located in a memory controller hardware. The write-back cache holds data being written back to main memory for a period of time prior to writing the data to main memory. If the data is cached in the write-back cache, the data is removed from the write-back cache and forwarded to the requesting processor. The cache coherency state in the coherency directory entry for the data is updated to reflect the current cache coherency state of the data based on the requesting processor's intended use of the data.

Abstract: Methods and apparatus are described for improving receiver performance in a multicarrier communication network in which an encoded symbol (250) is transmitted over a transmission channel (20) in the communications system. A model of the transmission channel (20) is estimated (718, 760), said model characterizing an effect of intercarrier interference on at least one carrier in the multicarrier system. The received symbol (250) is decoded (720, 762) using the estimated model to remove a predicted effect of intercarrier interference. A pre-processor (40) is also described for operation in conjunction with a communications receiver (30) in the network. The pre-processor (40) includes a channel estimator (42) operable to estimate at least one feature of the communication channel based on a received signal. The pre-processor (40) modifies the received signal dependent on the at least one estimated feature and provides the modified signal to the communications receiver (30).

Abstract: A system and method for automated optical dispensing includes a mobile client device configured to receive a frame selection, collect measurements based on an image of a patient, and receive a lens selection. Based on the parameters of the frame selection the mobile client device determines a position of a prescription within the lens selection. The mobile client device also runs a compatibility verification to determine if the frame selection and the lens selection are compatible, and submits an order to a manufacturer for the frame selection and the lens selection when the frame selection and the lens selection are compatible. The mobile client device may also create and submit claims to an insurance clearing house for professional services and contact lens products and services when applicable.

Abstract: The proposed system and associated algorithm when implemented improves the processor cache miss rates and overall cache efficiency in multi-core environments in which multiple CPU's share a single cache structure (as an example). The cache efficiency will be improved by tracking CPU core loading patterns such as miss rate and minimum cache line load threshold levels. Using this information along with existing cache eviction method such as LRU, results in determining which cache line from which CPU is evicted from the shared cache when a capacity conflict arises. This methodology allows one to dynamically allocate shared cache entries to each core within the socket based on the particular core's frequency of shared cache usage.

The delay circuit receives a composite input signal that exhibits a variable phase error and provides a plurality of selectable discrete delays. The control circuit is coupled to the delay circuit and receives a control signal whose value corresponds to the phase error associated with the composite input signal. The control circuit selects one of the plurality of selectable discrete delays responsive to the control signal, which is utilized to delay the composite input signal to provide a phase compensated composite output signal.

Abstract: A cylinder liner for an internal combustion engine provides a method of replacement of spent cylinder liners, wherein the cylinder liner includes a generally cylindrical body having a flange extending radially outwardly defining a shoulder. The shoulder provides a positive stop in an axial direction against a surface within a cylinder block of the engine. The body has an engagement portion adjacent the shoulder. The engagement portion is necked down from the flange and has lower and upper portions providing an interference fit within the cylinder block. The lower and upper portions of the engagement portion are separated from one another by a channel that extends substantially about the circumference of the body. The channel provides a passage for fluid flow between the lower and upper portions to facilitate cooling of the engagement portion.
