Patent CA-2297750-A1 (CA)
Inventor: TSYGANOV EDWARD N
IPC: H01L31/115
Filed: 1998-07-23
Abstract: The disclosed invention includes an apparatus and method for detecting radiation in a detector. The radiation to be detected ionizes the atoms in the intrinsic silicon lattice of the detector to produce a small signal of freed electrons. The small signal is then amplified by avalanche multiplication in a self-limiting manner by preventing the amplified electrons from traveling through a resistive layer, thereby reducing the electric field to limit the avalanche multiplication. An imaging system incorporating the new detector design is also disclosed.

IPC: G02F1/225
Filed: 1998-11-12
Abstract: The optical system comprises two optical paths (P1, P2), and an arrangement for changing the length of the two paths including two phase modulators (M1.  M2) one coupled to each of the paths. A driving system (Figure 3) applies power to the phase modulators to drive them in the same direction and to change the amount of power applied to the phase modulators in opposite directions so as to change the length of each optical path in a different direction. As a result, the relationship between the changes in the amount of power applied to the modulators and the resulting changes in the phase of light beams passing through the device becomes substantially linear.

Title: Ice cube bag and a method of producing ice cube bags
Inventor: VANGEDAL-NIELSEN ERLING
IPC: F25C1/24
Filed: 1998-12-09
Abstract: An ice cube bag comprises two sheet-shaped foil layers (12, 14; 12', 14') defining an outer periphery. A peripheral joint (20, 21, 21a, 21b) extends along the major part of the outer periphery of the foil layers, with the exception of a peripheral area constituting an inlet aperture of said bag (10). Their peripheral joint joins the foil layers together defining an inner chamber which is divided into several ice cube compartments defined by separate joints (22, 23, 24, 25, 29) of the foil layers. An inlet channel extends from the inlet aperture to the inner chamber of the bag hereby allowing admission from the surroundings to the inner chamber of the bag through the inlet channel. Each of said separate joints (22, 23, 24, 25, 29) is constituted by a number of individual joints (22, 23, 24, 25, 29), each of these individual joints (22, 23, 24, 25, 29) establishing a connection between the two sheet-shaped foil layers (12, 14; 12', 14') with such a joint strength and with such a limited area extension that the individual joint is not broken when the foil layers (12, 14; 12', 14') are exposed to a separation force, but provides a tearing apart or perforation (44) in one of the foil layers (12, 14; 12', 14') along the periphery of said individual joints.  Hereby an ice cube bag is obtained which is easy to open by tearing it apart.
