Patent CA-2033979-A1 (CA)
Inventor: ROGGENDORF PETER
IPC: G11B27/024
Filed: 1990-05-10
Abstract: A method of and apparatus for editing half-inch tape used for home recording of video material applies pulse-width modulation to prerecorded synchronizing pulses in predetermined time intervals. The interval is started with an eleven-bit header that is compatible with that of a commercially available system known as the VASS system. Time blocks are then encoded by pulse-width modulation with information identifying the particular recording session and the number of elapsed seconds minutes and hours since the beginning of the session. A check code completes the modulation during the interval for television systems such as PAL and SECAM that are adapted for fifty-Hz operation. For systems such as NTSC that operate at sixty Hertz, a ten-bit dummy code is added to complete the two-second interval. The code is entered without writing over the leading edge of the prerecorded synchronizing pulse, allowing the timing of those pulses to continue without interruption. Using this system, an editor can locate any desired interval and can then locate an individual frame within that interval by counting synchronizing pulses. The apparatus of the invention inserts and detects the header, inserts and detects the address code, inserts time signals in sequence, and detects a selected time interval and frame within that interval. An electronic circuit processes signals derived from the tape for input to a microprocessor which controls displays, insertion of codes, and advancing to a chosen edit location.

Patent CA-2038406-A1 (CA)
Inventor: SUSSMAN MARK L
IPC: C12Q1/06
Filed: 1991-03-15
Abstract: A method for rapidly identifying microorganisms by determining the rates of enzymatic hydrolysis of a plurality of substrates in the presence of at least one enzyme activity affecting agent, called an "affector" is provided. The substrates are selected from fluorogenic and chromogenic substrates to create a characteristic pattern of enzymatic cleavage rates by enzymes expressed by the unidentified microorganism. This characteristic pattern of enzymatic cleavage rates is a "fingerprint" of the unidentified microorganism when in the presence of the affector. The pattern of enzymatic cleavage rates for the unidentified microorganism is compared to a pattern of enzymatic cleavage rates of the same substrates in the presence of the same affector for one or more identified classes or subclasses of microorganisms. The unidentified microorganism is then identified as belonging to a class or subclasses of the known microorganisms which most closely matches the pattern of enzymatic cleavage rates in the presence of the affector.

Inventor: BECKEY THOMAS J
IPC: F24F11/00
Filed: 1991-05-02
Abstract: ABSTRACT          A comfort control system and method which determines the operating temperature set point for the environment to be controlled, in part by indirectly measuring the mean radian temperature of the environment.          A temperature sensor and relative humidity sensor sense the temperature and humidity of the environment to be controlled and provide electrical signals indicating the sensed values to a microprocessor.  A building load monitor either monitors the duty cycle of the heating/cooling system for the environment or senses the difference between the environment temperature and the outside temperature to generate a value indicative of the heating or cooling load on the building.  An example of a calculation formula to be stored in the microprocessor factors the selected operating temperature, the building load, the relative humidity, and selected constance.  The microprocessor determines the operating set point, compares the set point to the temperature of the environment, and generates a control signal for the heating/cooling system.  A method of controlling the comfort of an environment comprises the steps of sensing the air temperature and relative humidity of the environment, monitoring the building load of the environment, accessing the selected temperature of the environment and selected constant values for use in an operating set point calculation formula, calculating the operating temperature set point based on the sensed, monitored, and accessed values, comparing the operating temperature set point with the sensed room temperature, and generating a control system for the heating/cooling system based on the comparison.

Title: Doll
Inventor: FERRE JOSE MANUEL RODRIGUEZ
IPC: A63H3/28
Filed: 1991-05-31
Abstract: Involves a doll able to permit the introduction of cookie type slabs through the mouth, which simulates eating and having been eaten they fall by gravity to the bottom of an internal box, from which they can easily be extracted,  while at the same time it reproduces at intervals a series of sounds, in the form of changing phrases, which it emits through an acoustic device connected to an electronic circuit.    Outwardly it assumes the conventional  form of a baby,  and it contains in its interior an electromechanical assembly, including a set of wheels situated in line with the mouth, and when the cookie type slabs are introduced through the latter, they cause their intermittent entrainment and subsequent fall into the internal box.    In coordination with the entrainment of the cookies,  one hears externally through an acoustic device sounds in the form of phrases which begin to be emitted when the electronic circuit that regulates their  emission  is  connected and continue,  with different phrases, during the penetration of the cookie, to return to the original phrase after the cookie has finally fallen into the box.

Filed: 1992-08-18
Abstract: A cable (20) includes a waterblocking member (29) which includes a superabsorbent polymer. The superabsorbent polymer includes an ionic constituent which is characterized in that its solubility product is substantially higher than that of carboxylate and in that it has a lower reaction rate for forming an anhydride than does carboxylate. The ionic constituent may be selected from the group consisting of sulfate, sulfonate and phosphate and also includes a counter ion. Other constituents may include a carboxylate and a non-ionic group constituent. The superabsorbent polymer is such that the amount of crosslinking is sufficient to avoid the polymer going into solution, but is not so much as to affect adversely the water absorbency of the waterblocking member. Further, the superabsorbent polymer is much more salt tolerant and temperature tolerant than are prior art superabsorbent polymers.

Abstract: A self-regulating oscillator circuit and method are disclosed. Specifically, a method is described whereby an oscillator having an active device is operated. The oscillator is operated by providing a current through the active device, as well as through a reference device connected in series with the active device of the oscillator. A reference voltage across the reference device is sampled, and a regulated voltage is generated by adding a predetermined voltage to the sampled reference voltage. Finally, the regulated voltage is applied to the active device of the oscillator. In one circuit embodiment, the oscillator as described includes a gallium arsenide FET structure which cooperates with a resonant structure to produce a reflection-type oscillator. In addition, a regulator circuit is described including an isolating op amp which samples the reference voltage from the active device of the oscillator and provides its output to a voltage source device. The voltage source device adds an additional fisted voltage to the sampled voltage and the additional voltage is connected through a pn junction to provide a regulated output voltage. The regulated output voltage is connected to the active device of the oscillator, thereby maintaining the voltage drop across the active device to improve oscillator performance.
