Patent CA-2490600-A1 (CA)
Inventor: RICHARD JEFFREY MALCOLM
IPC: G01N19/04
Filed: 2004-12-20
Abstract: An apparatus and method for measuring a bond strength of a carton to reinforcement tape bonded thereto, the apparatus comprising a support post mounted on a base, and having two horizontal support rails welded to an upper end of the post. A pivotal lever arm is positioned horizontally beneath the support rails, and supports a weight which is able to move along the lever arm, the arm also having a clamp assembly at a distal end thereof. A threaded rod is positioned generally alongside the lever arm and, and has a movement plate placed thereon, which can engage the rear of the weight on the lever arm. The rod has a crank handle, which can be turned to move the plate into engagement with the weight and push it along the lever arm until the weight forces the lever arm to pivot downwardly, tearing the tape from the carton. Measurement markings on the apparatus can then be used to calculate the force required to separate the tape from the carton. To test a carton sample, a portion of reinforcement tape is peeled away from the carton so as to form a strip, which is placed between the rails. The strip is then clamped by the clamp assembly, and the handle is turned to move the plate into engagement with the weight and push it along the lever arm until the tape is torn from the carton, and the force measured.

Patent CA-2501527-A1 (CA)
Inventor: WRIGHT STEPHEN E
IPC: G01N33/50
Filed: 2003-10-10
Abstract: Disclosed are methods for detecting and localizing a cell-specific antigen i n a mammal, such as a human subject, comprising exposing peripheral blood mononuclear cells (PBMCs) of the mammal to an immunogenic peptide epitope of the antigen, under conditions for antigen-specific activation of T lymphocyt es in the PBMCs, thereby producing antigen-specific T lymphocytes that at least bind to the cell-specific antigen. Labeled antigen-specific T lymphocytes ar e administered to the mammal, typically without IL-2, either intraperitoneally or intravenously. The distribution of these cells in the mammal is determine d by imaging, thereby detecting and localizing cell-specific antigen in the mammal. Exposing PBMCs to the immunogenic peptide typically involves a cell- free peptide preparation and interleukin-2 (IL-2), but no additional cells such as antigen presenting cells (APC) separately pulsed with antigen. The antigen-specific T lymphocytes typically are cytolytic for cells expressing the cell-specific antigen and may comprise CD4+, CD8+, and/or CD45RO+ memory T cells.

Title: Mixed technology mems/bicmos lc bandpass sigma-delta for direct rf sampling
Inventor: LINDER LLOYD F
IPC: H03M3/02
Filed: 2004-02-12
Abstract: An improved sigma-delta modulator is disclosed. The sigma-delta modulator (100) utilizes Micro Electro Mechanical System (MEMS) technology coupled with on-chip LC networks (110,118). MEMS switches are used to switch capacitors and inductors in and out of the network to alter the center frequency and tuning range of the sigma-delta modualtor (100), thus eliminating active components in each LC network (110,118). Furthermore, the use of MEMS switches improves the Q of each LC network (110,118) relative to previous on-chip sigma-delta modualtor designs. The increased Q of each LC network (110,118) reduces or eliminates the need for active Q-enhancement circuitry and improves the inherent filter shape within the loop of the sigma-delta modulator (100). In addition, the distortion of active compoenmtns with the loops (146,146', 148, 148') of the sigma-delta modulator (100) also is improved. The addition of a decimator 252 to the chip presents a complete single chip LC sigma-delta analog-to-digital converter 250.
