Abstract: A filter trap into which waste water can be dumped to separate particulate matter from the water. A sensor senses when the liquid level in the filter trap rises above a predetermined level, and triggers an alarm to indicate the filter basket is full of particulate matter and must be removed to dispose of the contents. The withdrawal of the filter basket from the filter trap causes the inlet thereto to automatically close so that waste water cannot be dumped into the filter trap when the filter basket has been removed. A sensor senses when the filter basket has been removed to provide a visual indication thereof.

Abstract: A hierarchical memory request stream arbitration technique merges coherent memory request streams from multiple memory request sources and arbitrates the merged coherent memory request stream with requests from a non-coherent memory request stream. In at least one embodiment of the invention, a method of generating a merged memory request stream from a plurality of memory request streams includes merging coherent memory requests into a first serial memory request stream. The method includes selecting, by a memory controller circuit, a memory request for placement in the merged memory request stream from at least the first serial memory request stream and a merged non-coherent request stream. The merged non-coherent memory request stream is at least partially based on an indicator of a previous memory request selected for placement in the merged memory request stream.

Abstract: A system and method for data allocation in a shared cache memory of a computing system are contemplated. Each cache way of a shared set-associative cache is accessible to multiple sources, such as one or more processor cores, a graphics processing unit (GPU), an input/output (I/O) device, or multiple different software threads. A shared cache controller enables or disables access separately to each of the cache ways based upon the corresponding source of a received memory request. One or more configuration and status registers (CSRs) store encoded values used to alter accessibility to each of the shared cache ways. The control of the accessibility of the shared cache ways via altering stored values in the CSRs may be used to create a pseudo-RAM structure within the shared cache and to progressively reduce the size of the shared cache during a power-down sequence while the shared cache continues operation.

Abstract: A separator provides improvements for better separation of an effluent into constituent parts and greater ease of use. A tapered basket provides improved flow and better filtration. A baffle directs effluent into the basket with greater force. An asymmetrical flange prevents mis-orientation the basket and baffle. An improved oil valve provides a locking mechanism to prevent dislodging of the valve during cleaning. An alternative valve uses a sensor to sense an oil/water interface and close the oil valve appropriately. A top seal prevents leakage of effluent at connection points with the lid of the housing. An underground unit allows below floor level installation of the separator. A bidirectional unit can be reversed to provide flow in either direction. A dual purpose tank can be used to store both separated oil and oil from operations for common removal.

Abstract: A first portion of a communication link is operated in a power savings mode at the same time that a second portion of the communication link is operated in a normal operational mode. For the first portion, a refresh mode is entered from the power savings mode in which one or more training patterns are transmitted over the first portion, while the second portion remains in the normal operational mode. An indication when to activate and deactivate the refresh mode may be sent over the second portion of the communication link. The refresh mode may be periodically entered from the power savings mode based on an interval register specifying the amount of time the communication link should remain in the power savings mode before a refresh occurs. In addition, the amount of time spent in the refresh mode may be programmable.

Abstract: A computer system includes a first and a second integrated circuit coupled by a communication link. The communication link operates in a power savings mode in which data is not transmitted over the link. Periodically, the communication link enters enter a training phase in which training patterns are transmitted over the communication link for a predetermined time period. The communication link returns to the power savings mode after the predetermined time period has elapsed. At least one sideband signal, separate from the communication link, and coupled between the first and second integrated circuits, is used to indicate when to enter the training phase from the power savings mode and exit the training phase and return to the power savings mode.

Abstract: A power-actuated closure system is disclosed. The system includes a power-actuated closure panel having a leading edge. One or more non-contact optical sensing system(s) is/are affixed to the power-actuated closure panel. The sensing system is adapted to detect the presence of an obstruction in proximity to and in advance of the leading edge of the closure panel. The system also includes a control system that selectively controls the motion of the closure panel in response to signals received from the sensing system.

Abstract: A software tool for manufacturing system performance analysis includes modeling and analysis functions. A modeling isolation layer provides user access to the analysis capabilities through object-based model building and analysis invocations. Various model, performance and higher level analyses are performed through analysis modules kept separate from any end-user application programs by the modeling isolation layer.

Abstract: It is an object of the present invention to reduce a playback distortion and make it possible to output a large volume sound in a low frequency area, without increasing the diameter of subwoofer or woofer. A speaker device comprises a speaker unit, a diaphragm of the speaker unit disposed at an opening of a baffle plate, and a compression board disposed opposite to a radiation surface of the diaphragm in a manner such that a predetermined interval is formed between the compression board and the baffle plate.

Abstract: A battery charger measures an average battery temperature at a pre-determined timing for a first fixed period after start of charging. If the number of consecutive positive second derivatives of battery temperature is four, charging is discontinued. If the number of consecutive positive second derivatives of battery temperature is not four, the charging is carried out continuously for a pre-determined secondary period.
