Patent CA-2140436-A1 (CA)
Title: Sensor devices
Inventor: VADGAMA PANKAJ M
IPC: C12M1/40
Filed: 1993-07-23
Abstract: Sensor devices for examining fluid samples having, between the sample under examination and a detector, a membrane made of polyvinyl chloride in un-plasticised form. This membrane material acts as a barrier to paracetamol and sugars but is permeable to hydrogen peroxide and to oxalate, so these species can be determined after passing through the membrane. When they are not present as such in the sample, they may be formed from analytes which are sought (e.g. by enzymic action, which is especially applicable to the determination of glucose, using an oxidase enzyme). The membranes may be made by solvent casting, conveniently to a thickness of 10 to 40 µm, and used in electrolytic systems with a platinum anode. The membrane material can be formed into multi-layer membranes, which may incorporate layers of material to protect it or modify the permeability, or added materials for example enzymes.

Patent CA-2159189-A1 (CA)
Title: Digital controlled xtal osc
Inventor: LIEDBERG NILS PER KE
IPC: H04J3/06
Filed: 1994-03-24
Abstract: According to the present invention, an unlimited number of steps or increments of given size are obtained in a delay line for phase alignment of, for instance, the signal from a crystal oscillator by momentarily switching between two parallel delay lines.  One delay line operates as an active or enabled delay line while the other line is disabled or inactive.  It is ensured at the same time that the inactive delay line produces a signal which has the same relative phase as the active delay line, this absolute phase differing by N x 2.pi. , where N is a positive or a negative integer other than zero.  The inventive method and the inventive device enable the active delay line to operate constantly within its regulation range and the phase of the local oscillator can be kept continuously locked to the phase of the reference signal.  The inventive device also includes an oscillator, a phase comparator and counter logic and a further phase comparator and a selection circuit for signal selection from that one of the two parallel delay lines that has been placed in its active mode.
