Title: For driving step motors without overshoot
Inventor: MASKE RUDOLPH J
IPC: H02P8/10
Filed: 2000-10-13
Granted: 2011-02-15
Abstract: A method and apparatus for driving a stepper motor such that when the motor is stepped, the velocity of the motor is substantially zero upon reaching a new stepped position, thereby eliminating overshoot and ringing, and the wasted energy associated with these effects. The method comprises energizing at least one of the stepper motor windings at a predetermined current level for a predetermined step time, wherein the current level is determined as a function of the step time and dynamic single-step response characteristics of the stepper motor and load so that the motor velocity is substantially zero when the adjacent stepped position is reached. At this point, the stepper motor windings that were energized to make the rotor of the motor move are de-energized, whereupon the rotor is held in place by the inherent detent torque of the stepper motor. Since the velocity of the motor is substantially zero when the adjacent stepped position is achieved, there is no overshoot, and thus ringing is eliminated.

Title: Uv-c sterilizer
Inventor: DEAL JEFFERY L
IPC: A61L2/10
Filed: 2001-02-16
Granted: 2008-04-08
Abstract: An ultraviolet area sterilizer (UVAS) is mobile or stationary. The UVAS is positioned in a room, such an operating room or intensive care unit. Motion detectors sense movement, to assure that personnel have evacuated the space to be sterilized. Subsequently, UV-C generators, such as a bank of mercury bulbs, generate intense levels of UV-C. An array of multiple UV-C sensors scans the room, and determines the darkest area, or the area reflecting the lowest level of UV-C back to the sensors. A Microcontroller contained in the device calcu- lates the time required to obtain a bactericidal dose of UV-C reflected back from darkest area. Once a bactericidal dose has been reflected to all the sensors, the unit notifies the operator and shuts down. By relying on reflected doses rather than direct exposure, the UVAS is able to sterilize or sanitize all surfaces within the room that are within view of an exposed wall or ceiling.

Title: Hidden markov modeling for radar electronic warfare
Inventor: LAVOIE PIERRE
IPC: G01S7/36
Filed: 2002-09-06
Granted: 2008-12-02
Abstract: The present invention relates to a method for identifying modem radar systems.  A  finite state automaton comprising a finite set of states and a set of transitions from state to state that occur in dependence upon an input signal is provided for modeling the radar system. The finite state automaton produces a sequence of output symbols from an output alphabet in dependence upon the state transitions such that the sequence of output symbols corresponds to a received electromagnetic signal emitted from the radar system. The finite state automaton is then transformed into a hidden Markov model such that a sequence of observation symbols produced from an observation alphabet by the hidden Markov model is equal to the sequence of output symbols. The method provides powerful tools for solving electronic warfare problems such the classification problem, the decoding problem, the prediction problem and the training problem. Describing the radar system as a finite state automaton and transforming it into a hidden Markov model provides flexibility and preserves a maximum of information provided by the observed signals. The new method is compatible with conventional receiver front-ends and allows integration into a wide range of legacy ES, EA and ELINT systems. The only hardware requirement is a fast processor with sufficient memory.

The arcuate layers organize the splices, so they are readily identifiable and accessible. In addition, the arcuate layers make efficient use of the limited space available for storing the splices. The joint box includes a center shelf longitudinally dividing the joint box into two compartments. To accommodate more splices, an arcuate retainer may be provided in each compartment by mounting an arcuate retainer on each side of the shelf.
