Title: System for transmitting and verifying alarm signals
Inventor: PALKA MARK STEPHEN
IPC: G06F11/32
Filed: 2000-12-07
Granted: 2010-02-23
Abstract: A system for transmitting and verifying alarm signals over a TCP/IP network includes: an alarm panel hosting an alarm client and verification server and connected to at least one alarm sensor, alarm verification means and a TCP/IP network, an alarm monitor server and a verification station connected to each other and to the TCP/IP network. If the alarm client detects an alarm situation, it transmits an alarm signal to the alarm monitor server. The alarm signal contains information on how to contact the verification server. If it is necessary to verify the alarm signal, the alarm monitor station sends the alarm verification station a verification request containing the contact information for the verification server. The alarm verification station contacts the verification server and obtains the verification information available from the alarm verification means.

Abstract: A diesel engine, having a plurality of individually controllable fuel injected cylinders, is operated in a skip firing mode to reduce smoke emissions during low power operation. The system senses certain identified engine operating parameters and when these parameters exceed predetermined thresholds for a predetermined time, then the skip firing is implemented. In another embodiment, it is possible to implement several different skip firing patterns dependent upon engine performance. Upon implementation of skip firing, the engine timing angle is reset by a fixed angle and a multiplication factor is included in the speed loop integrator to ensure that the appropriate fuel volume value is injected into each cylinder immediately upon initiation of skip firing. Skip firing is then disabled when another set of predetermined conditions is satisfied.

Title: Apparatus for volatilizing and dispensing a chemical
Inventor: HOUSER DAVID J
IPC: A01M1/20
Filed: 2000-05-19
Granted: 2005-01-04
Abstract: An air quality modification apparatus for dispensing a volatile material, such as for scenting the air, controlling pests, allergen control, or the like, includes an electric motor having a rotor and a coil.      When electric current is applied, the coil produces both heat and an electromagnetic field that causes rotation of the rotor. A source of the volatile material is located adjacent to the coil so as to be volatilized by the coil's heat. An impeller, attached to the rotor, moves air across the volatile material and blows the vapors away from the apparatus.      Energy efficiency is provided by employing the electric motor coil as the source of heat to vaporize the volatile material. Also disclosed is a refill supply of a volatile material for use with such an air quality modification apparatus.

Title: Method for collecting and preserving semen
Inventor: PRIEN SAMUEL D
IPC: A01N1/02
Filed: 2001-03-01
Granted: 2010-06-01
Abstract: A method for collecting and preserving semen of various animals including humans, canines, porcines, bovines, ovines and others involves collecting the semen into a collection vessel where the collection vessel is provided with an extender solution for the semen prior to its collection. Moreover, the extender is preferably maintained at a temperature close to normal body temperature of the species being collected over the time period of its collection. The extender is chosen to buffer the pH of the semen sample and to be isotonic with the semen. The volume of the extender in the collection vessel is preferably chosen such that the semen volume is initially diluted with twice its volume extender solution and some period thereafter the extended semen sample is diluted again at the same ratio. Collection into warmed extender media lessened the cold and pH shock to the spermatozoa, as shown by improved semen parameters. The extender solution is preferably rich in calcium ion. A collection vessel resembling an inverted Y is used for collecting distinct semen samples for comparative study.

Abstract: Two layers of a flexible and essentially impervious material are sealed to each other at their edges and are otherwise separate from each other so as to form an interior portion. Many lengths of thread connect the layers together at numerous points throughout the interior portion. The length of the thread that is between the layers is relatively short and the thread connects the layers at a sufficient number of points to restrain the layers and hold them in a spaced relationship when the interior portion is inflated with air. Applying modest air pressure to the interior portion produces a lightweight structure of sufficient stiffness that is attached to the rear ends of trunk trailers to improve airflow and reduce drag at highway speeds.
