Patent CA-2197815-A1 (CA)
Inventor: ABRAMOVICI MIRON
IPC: G01R31/28
Filed: 1997-02-18
Abstract: A method of increasing the testability of sequential circuit designs with use of a clock transformation technique. Circuit states which are difficult to reach, but are nonetheless required to detect at least one fault of the circuit, are automatically identified. In accordance with one illustrative embodiment, estimations of joint line probabilities are compared with a preselected threshold value to identify hard-to-reach states. Then, commonly clocked flip-flops which must be simultaneously assigned values in order to reach the identified states are partitioned into independently clocked groups of flip-flops. In this manner, hard-to-reach circuit states are transformed into easy-to-reach states, which, in turn, results in transforming difficult-to-detect faults into easy-to-detect faults.

Filed: 1997-04-09
Abstract: A system for applying pressurized anhydrous ammonia to soil.  The system includes a tank for containing the pressurized anhydrous ammonia.  An anhydrous ammonia meter is in fluid communication with the tank for dispersing controlled amounts of the anhydrous ammonia.  A pressurization unit is also in fluid communication with the tank.  The pressurization unit defines a pressurization chamber through which anhydrous ammonia from the tank is circulated.  A heating system cooperates with the pressurization unit to heat the anhydrous ammonia within the pressurization chamber. The heated anhydrous ammonia is returned from the pressurization chamber to the tank.  By adding the heated anhydrous ammonia to the tank, the pressure within the tank is stabilized or even slightly increased.

Abstract: Disclosed is an optical communication system enabling communication between several co-existing transmitting and receiving stations. In order to allow communication between the co-existing stations, a robust physical layer header (RPLH; 50) is employed which can be understood by all participating stations. This robust header (50) at least comprises a preamble (52) consisting of frames forming a periodic sequence of pulses, the number of slots per frame and the frame content being known to all participating stations. The preamble (52) serves for relative synchronization and carrier detection of the receiving stations.  The robust header (50) further comprises a unique synchronization word (53) used for absolute synchronization of the receiving stations. This synchronization word (53) is followed by a control field (59) of fixed length and known structure. By means of this control field (59) the receiving stations are informed which modulation method will be used for the transmission of data. Under certain circumstances it is also useful to provide other control information in said control field (59) for communication link and network control. Furthermore, information may be exchanged to allow negotiation and/or adaptation of the data rate used for transmission. This allows to optimize the throughput depending on the conditions (quality) on the channel.

IPC: H05B37/03
Filed: 1998-09-09
Abstract: An electric series circuit with plural loads such as light bulbs connected in series and plural solid state switching devices, with each switching device connected in parallel with one of the loads. Each switching device conducts current when the load that it is connected in parallel with does not conduct current because the load is burned out. The solid state switching means may be any device. with a breakthrough voltage which is high enough that it does not conduct when all of the loads conduct current normally. When one of the loads is burned out, that load does not conduct current and the entire line voltage appears across the switching means in parallel with the burned out load. The switching means breaks down. Accordingly, the switching means conducts current and current flows to the remaining loads. Accordingly, the remaining light bulbs in a string of light bulbs continue to light. The burned out load may be immediately detected and replaced. The switching means may be a sidac. Alternatively, a combination of an SCR and a zener diode controlling the gate of the SCR are also disclosed as the switching means. A diac may replace the zener diode.

Abstract: A method of preventing or inhibiting undesired uterine contractions in a female individual by administering a pure eutomer of an adrenergic beta-2 agonist which relaxes uterine smooth muscle, while eliminating side effects caused by the distomer. The method is particularly useful in treating both pregnant and non-pregnant subjects that have demonstrated a propensity for undesired uterine contractions, while reducing side effects in the patients and/or their fetuses, such as bronchial hyperreactivity, tremor, nervousness, shakiness, dizziness, increased appetite and cardiac tachycardia. Importantly, administration of a pure eutomer also eliminates undesired contractions of the uterine smooth muscle while avoiding the uterine hyperreactivity that has now been found to be induced by the S- or SS-isomers of beta-2 agonists.
