Patent CA-2274224-A1 (CA)
Title: Explosive fragmentation process
Inventor: GARG AJAY K
IPC: C09K3/14
Filed: 1998-01-14
Abstract: Porous ceramic particles can be fragmented by generating a gas inside the pores at a sufficient pressure to cause the particles to be fragmented. The preferred way of generating the pressure is by immersing the particles in a liquid that at ambient temperatures and pressures is a gas until the liquid is absorbed into the pores and thereafter rapidly changing the conditions such that the liquid becomes a gas resulting in explosive fragmentation of the ceramic particles.
Patent CA-2274856-A1 (CA)
Inventor: BEELEY JOHN RONALD PAUL
IPC: H03K3/335
Filed: 1997-12-12
Abstract: A fast voltage ramp generator comprises a chain of transistors connected collector to emitter in series, and biased to avalanched switching mode. A respective transformer secondary is connected to apply a switching pulse across the base emitter junction of each transistor of the chain, to effect avalanche switching of the chain. The transformer secondaries are the secondaries of discrete transformers with respective primaries connected in series. The transformers are formed of ferrite beads having plated through holes constituting the secondaries of the transformers. The beads are threaded on an insulated conductor which constitutes the series connected primaries of the transformers.

Patent CA-2282194-A1 (CA)
Inventor: SUN SEY-SHING
IPC: G09F13/20
Filed: 1999-09-10
Abstract: The luminance of a phosphor suitable for an alternating current thin-film electroluminescent device is substantially improved according to the present invention by including an alkali halide. The alkali halide included within the bulk of the phosphor material results in providing a significant number of trapping states which trap free electrons within the phosphor material. The addition of the trapping states (added defects) within the bulk tend to control the electrical and optical characteristics of the phosphor material.      This reduces asymmetric light output characteristics of traditional phosphor material, reduces asymmetric current movement within the phosphor material, and decreases the influence of the interfaces between the phosphor material and insulating materials resulting in decreased aging and increased brightness.

Patent CA-2294698-A1 (CA)
Inventor: KOO YUEN-YIN L
IPC: H04B1/7097
Filed: 2000-01-11
Abstract: The present invention is an apparatus and method for calculating the transmit power of a mobile station by including an interference correction term in every access probe of the mobile station to more correctly estimate the path loss. The interference correction term accounts for the presence of base station pilot signals when calculating the transmit power. Importantly, the present invention is implementable in any CDMA based communication system. In an exemplary embodiment of the present invention, a mobile station implements open loop power control by determining an interference correction term that accounts for the detection of non-active-set pilot signals, thermal noise, or non-CDMA interference, one or more of which are indicated by the detection of a given receive threshold. The mobile station then adjusts its open loop transmit power (access probe power in access state) based on the interference correction term. In a further embodiment, the interference correction term is limited to a maximum level of correction for the case when an active pilot is not detected. In an additional embodiment, the non-active-set pilot power is approximated to all received pilots other than the largest active-set pilot.

Abstract: L'invention concerne un dispositif (20), système ou analogue à aileron destiné à être monté sur une planche de snowboard ou des skis pour en améliorer les performances, la manoeuvrabilité, le répondant et l'équilibre. Les ailerons, qui sont conçus pour être facilement montés sur une planche de snowboard, sont pourvus de lames (28) qui permettent de contrôler la trajectoire de la planche dans diverses conditions d'enneigement, de la poudreuse, à la neige dure et à la glace. Chaque aileron est constitué d'une plaque (36) de fixation destinée à positionner facilement les ailerons (20) sur une planche, et d'une lame montée rotative sur un axe (30) à ressort. L'axe rotatif à ressort permet aux lames de fléchir au contact d'une surface dure de manière à s'auto-ajuster constamment selon les conditions d'enneigement. L'ajustement en profondeur se fait grâce à une vis ailée (60) qui permet de régler la position de rotation de l'axe et donc, la profondeur avec laquelle la lame (28) dépasse de la surface inférieure de la planche de snowboard. En faisant tourner la vis ailée (60), un skieur peut faire varier la profondeur de la trace faite par la lame (28) sur chaque aileron individuellement.
