Patent CA-2331002-A1 (CA)
Title: Analog storage for a cmos array
Inventor: SCOTT-THOMAS JOHN
IPC: H04N5/335
Filed: 2001-01-10
Abstract: The image sensor comprises an analog memory array integrated on a die with a CMOS sensor array and coupled to the sensor array for receiving light intensity signals from the sensor array. The sensor array may comprise light sensitive pixels arranged in rows and columns equal in number or greater than the number of memory cells in the memory array which are also arranged in rows and columns. The memory cells may be grouped into one or more distinct memory arrays. The image sensor operates in a rolling shutter mode which closely approximates electronic frame capture since the transfer process can be made sufficiently fast. This CMOS  image sensor is particularly advantageous since it can be produced without requiring a special manufacturing process and still maintains a high performance level.  Certain features of the image sensor along with the optical isolation of the memory array result in longer hold times in the memory cells by reducing the effects of light piping, optically enhanced sub-threshold current, and photo charge in the substrate.  Structural variations in the sensor and the memory arrays may be compensated by double sampling the data from the sensor array.

Abstract: An induction broiler (10) which includes a non-metallic support plate (20) a nd a hot grate (11) for broiling food thereon. The grate (11) includes a plurality of spaced apart elongated metallic bars (12). Each elongated metallic bar (12) has a base portion (16) disposed above and adjacent to the  non-metallic support plate (20) and a food heating surface (15) opposite the  base surface (17). The induction broiler (10) further includes at least one induction heating coil (22) connected to a power supply (30) and mounted bel ow and adjacent to the non-metallic support plate (20). During operation, the induction heating coils (22) generate an alternating magnetic field which is  coupled into the grate (11) across the support plate (20). As a result, current flow is induced through the elongated bars (12) which, in turn, results in the heating of the food heating surface (15) of each elongated ba r (12).
Patent CA-2332244-A1 (CA)
Inventor: DEMPSEY ROBERT TIMOTHY
IPC: E21B43/12
Filed: 2001-01-25
Abstract: An artificial lift assembly is suspended from a string of conduit in a well inside a well casing. An encapsulation module is independently suspended from the conduit and encases the pump assembly with a jacket. A series of well fluid conditioning tools are mounted to the lower end of the jacket, including a tubular screen, a desander located behind the screen, a string of disposal conduit extending below the desander, and a nucleation device located above the desander. The entire weight of this fluid conditioning equipment is completely supported by the jacket and the conduit. The encapsulation module is completely sealed so that the well bore fluid is limited to entering the module and pump through the screen. The screen removes larger contaminants from the fluid such as rubber and trash.  After the fluid passes through the screen, it enters the desander where solid matter such as sediment is removed from the fluid and eliminated through the disposal conduit. Finally, the fluid enters the nucleation device where its scale is decomposed. After these three clarifying phases, the fluid enters the pump assembly and is pumped to the surface.

Filed: 2001-07-09
Abstract: A watercraft having a turnable (i.e., pivotable) planing surface, preferably with at least one skeg projecting generally vertically downward from the planing surface. This structure is designed to provide improved steering performance of watercraft, particularly jet-powered boats, while minimizing drag. The turnable planing surface is formed by a bottom surface of a steering pad mounted beneath a jet propulsion unit. In one embodiment, the water jet propulsion unit is fixed (i.e., not turnable) and the skeg-bearing planing surface is turnable relative to the water jet propulsion unit. In another embodiment, the water jet propulsion unit is turnable relative to the hull centerline (e.g., in the manner of an outboard engine) and the skeg-bearing planing surface is fixed relative to the water jet propulsion unit (i.e., the skeg-bearing planing surface turns in unison with the jet propulsion unit). The planing surface may optionally have strake-like sides.

Filed: 1999-12-09
Abstract: A telecommunications system and method is disclosed for enabling a General Packet Radio Ser-vice (GPRS) node, namely a Serving GPRS    Sup-port Node (SGSN) within a cellular network, to be able to handle requests for Location Services (LCS) for a GPRS mobile station (MS) in paral-lel to other existing transactions such as delivering short messages or engaging in session management activity, e.g., data call connection. A new LCS  transaction type can be introduced in the Connec-tion-Management (CM) sub-layer of GPRS in the SGSN and the GPRS MSs to handle requests for LCS in parallel to other offered services. LCS can be multiplexed together with other existing func-tions in GPRS by allocating a new Service Access Point Identifier (SAPI) to LCS within the Logical Link Control (LLC) sub-layer of the GPRS.    Alter-natively, when a common LLC SAPI is used be-tween different CM-sublayer functions,then a dif-ferent protocol discriminator (PD) can be allocated for LCS.
