Patent CA-2516010-A1 (CA)
Title: Heavy duty electronic brake stroke indicator
Inventor: HILDING ROBERT J
IPC: F16D66/00
Filed: 1994-11-29
Abstract: Electronic stroke indicators have sensor structures (34, 60, 80,110) which are incorporated into a stone shield (28, 62, 82, 116) for a brake actuator (20). The incorporation of the sensor (34, 66, 119) stone shield (28, 62, 116) protects the sensor (34, 60, 119) and its associated wires (54, 69, 121) and contacts from damage by the other components in the brake actuator (20). In particular, the spring is typically maintained one of contact with any of the electric portions of the electronic stroke indicator, thus prolonging the life of the electronic stroke indicator. In further features of this invention a magnetic sensor (34) may monitor the position of magnetic portions (36) on a piston rod (32). Alternatively, a pair of electric contact switches (96, 98) may be serially contacted by a structure on the piston rod (94) as the brake moves further out of stroke. The two electric contacts (96, 98) provide different signals to an operator in a vehicle cab such that signals of the level of out-of-stroke conditions are provided to the operator. In a further embodiment, a load cell (119) monitors the compression in a spring (112) in the brake housing (111) to provide an indication of an out-of-stroke condition.

Title: Strain energy shuttle apparatus and method for vibration energy harvesting
Inventor: CLINGMAN DAN J
IPC: H01L41/113
Filed: 2004-07-30
Abstract: An apparatus for use in low frequency vibration energy harvesting (VEH) and with actuators requiring a low deflection force. The apparatus includes a piezo flexure that is loaded with a compressive pre-load force to place the piezo flexure under compression. The piezo flexure may be supported at an intermediate point or at one end thereof. The compressive pre-load force flexes the piezo flexure into one or the other of two stable positions, these positions being offset on opposite sides of a longitudinal centerline representing the position of the piezo flexure that would be produced without the compressive pre-load force applied thereto. The compressive pre-load effectively provides a negative spring constant which ~softens~ the piezo flexure and enhances a responsiveness of the piezo flexure to low frequency vibration energy. The piezo flexure also operates over a much wider frequency bandwidth than conventional systems incorporating a tip mass.

Patent CA-2542497-A1 (CA)
Inventor: TOMPKIN WAYNE ROBERT
IPC: B42D15/10
Filed: 2004-11-02
Abstract: A diffractive security element has a half-tone image comprising diffractive structures in a reflection layer, which are embedded in a layer composite between a transparent embossing layer and a protective lacquer layer. The half-tone image is divided into image elements of at least one dimension less than 1 mm, wherein the surface of each image element is divided up into a background field and an image element pattern. The proportion of the image element pattern to the surface of the image element determines the surface brightness of the half-tone image at the location of the image element. The background field has a first diffractive structure from which the image element pattern differs by its light-modifying effect. Pattern strips of a width of up to 0.3 mm additionally extend over the surface of the half-tone image. The pattern strips occupy a small proportion of the surface of the background fields and/or the image element patterns and produce coloured strips on the half-tone image.
Patent CA-2543919-A1 (CA)
Inventor: JIANG TAO
IPC: A61M36/14
Filed: 2004-10-20
Abstract: A generic structure for the peptides of the present invention includes A - X -B -C, where C is a cargo moiety, the B portion includes basic amino acids, X  is a cleavable linker sequence, and the A portion includes acidic amino acids.  The intact structure is not significantly taken up by cells; however, upon extracellular cleavage of X, the B - C portion is taken up, delivering the cargo to targeted cells. Cargo may be, for example, a contrast agent for diagnostic imaging, a chemotherapeutic drug, or a radiation-sensitizer for therapy. Cleavage of X allows separation of A from B, unmasking the normal ability of the basic amino acids in B to drag cargo C into cells near the cleavage event. X is cleaved extracellularly, preferably under physiological conditions. D-amino acids are preferred for the A and B portions, to minimize immunogenicity and nonspecific cleavage by background peptidases or proteases.
