Title: A microwave multiphase detector
Inventor: BROWN ANTHONY KEVIN DALE
IPC: H03L7/085
Filed: 1996-11-13
Abstract: A microwave multiphase detector for demultiplexing and regenerating data from an incoming data stream includes N data channels and has a data rate R. For recovering data corresponding to a channel M, a detecting unit receives the data stream, detects a sampling phase corresponding to a data transition on channel M and generates a phase width modulated (pwm) pulse, phase modulated with the sampling phase. A digital to analog (D/A) conversion unit converts the pwm pulse to a contributing control voltage and a data regeneration unit provides a recovered data bit for channel (M). The detector is supplied with N variants of a local clock signal with a rate R/N, each variant being phase displaced with ~360°/N from the adjacent variants. A counterbalancing unit is also provided for each channel, such that if a pwm pulse is indeed generated, the contributing voltage for that pulse is compensated for with a balance pulse of opposed amplitude. In this way, the sampling phase corresponding to the respective M data channel may be adjusted by varying the ratio between the amplitudes of the pwm pulse and the balance pulse.

Title: Optocomponent capsule having an optical interface
Inventor: STEIJER ODD
IPC: H01L31/0203
Filed: 1995-10-19
Abstract: In encapsulating an optocomponent with a plastics material an MT-connector compatible interface is obtained having bores (107) for guide pins in the wall of the capsule and optical connection surfaces (110). These bores (107) are obtained from mould cavity guide pins which are used for aligning the optocomponent in a mould cavity in a mould in the moulding operation of the encapsulating material on top of the component. In order to achieve a good accuracy in the positioning of the component during the moulding operation the mould guide pins are as short as possible and end directly behind the component where they are supported by projections extending from each mould half. Thus cavities (109) are created extending straight through the capsule (105) behind the component. The cavities (109) allow that the guide pin bores (107) are cleansed and that material residues are removed after the moulding operation. Further, the cavities (109) can be used for spring clamps which are used for retaining the optocomponent capsule (105) at an optical connector having a similar interface. The clamps can then have tongues which are inserted in the cavities (109) and which, in addition, can be provided with holes, through which the guide pins can be pushed to safe-guard the clamp against being lost.

Patent CA-2219474-A1 (CA)
Inventor: BORCUTI MAXIM
IPC: G01N27/04
Filed: 1997-12-24
Abstract: The invention consists of a portable instrument, of a very high accuracy, which measures the soil moisture and which can be calibrated (gauged) for the use in the most different conditions, in function of necessities. It is a multifunctional gauge of a compact construction very well adapted to the purpose it was conceived for. In order to measure the soil moisture, the gauge uses the proportionality between the soil humidity contents and its electric conductivity. The information is displayed by a series of LED-s. In contrast with the use of a needled pointer, this mode of displaying gives a great endurance to the gauge. When it is switched to the ~ALARM~ mode of functioning, the gauge detects any decrease of the soil moisture level under a preset threshold, depending on the type of plant signaling either optically or acoustically, at choice.  The gauge uses a measuring probe of an original conception, made of conducting tracks specially conceived for this measurement.
