Filed: 1988-03-21
Granted: 1992-10-20
Abstract: ABSTRACT     Apparatus for automatically controlling the ready-to-drive condition while maintaining ready-to-start temperature of a single or multiple gas, gas-diesel or diesel engine in automobile uses an electronic circuit linked to various sensors including a temperature sensor, a vibration sensor, and a motion sensor. Signals generated by the temperature sensor are used to turn the engine on and off based on predetermined maximum and minimum temperature. The temperature sensor output is also used to automatically reset the engine. For multiple engines, this sensor can be used to actuate a secondary engine if the primary engine reaches a predetermined maximum temperature and switch back to the primary engine when the engine temperature drops to a predetermined low temperature. Signals generated by the vibration sensor are used to monitor engine activity. For multiple engines, the vibration sensor output determines when control is switched from the primary engine to the secondary engine or vice versa, and also determines the engine cranking time for both multiple and single engines. Signals generated by the motion sensor are used to disable engine activity when accidental motion is detected of the automobile. Control means are provided for regulating several attempts at automatically starting the engine of an automobile with the engine parameters being changed each time. The starting mechanism is reset when the engine starts, and is disabled temporarily if a predetermined number of failed attempts to start have been made. Provision is also made for restarting the engine if stops running and if predefined motor conditions exist.

Title: Adaptive threshold voiced detector
Inventor: THOMSON DAVID L
IPC: G10L25/93
Filed: 1988-03-29
Granted: 1995-07-04
Abstract: Apparatus for detecting a fundamental frequency in speech by statistically analyzing a discriminant variable generated by a discriminant voiced detector (102) so as to determine the presence of the fundamental frequency in achanging speech environment. A statistical calculator (103) is responsive to thediscriminant variable to first calculate the average of all of the values of thediscriminant variable over the present and past speech frames and then to determine the overall probability that any frame will be unvoiced. In addition, the calculator informs two values, one value represents the statistical average of discriminant values that an unvoiced frame's discriminant variable would have and the other value represents the statistical average of the discriminant values for voice frames. These latter calculations are performed utilizing not only the average discriminant value but also a weight value and a threshold value which are adaptively determined by a threshold calculator (104) from frame to frame. An unvoiced/voiced determinator (105) makes the unvoiced/voiced decision by utilizing the weight and threshold values. (FIG. 1)

Granted: 1992-06-23
Abstract: Abstract of the Disclosure The present invention is an automatic garage door operator with a two button portable controller enabling a secure mode and control of a load remote from the door operator.  In accordance with the normal operation of the secure button,  actuation when the garage door is closed toggles a secure mode between secure and non-secure states.   In the secure state the automatic garage door operator does not move the door upon receipt of a door signal.   To open the door when in the secure state the operator must first press the secure button to enter the non-secure state and then press the door button to open the door.  The secure button has a secondary function when the garage door is open and the secure state is prohibited.   Actuation of the secure button when the door is open toggles the state of a load remote from the automatic garage door operator between an on state and an off state.  This control is achieved via a signal modulated on the electric power main.

Title: Xenon lamp particularly suited for automotive applications
Inventor: DAVENPORT JOHN M
IPC: H01J61/86
Filed: 1989-02-02
Granted: 1992-08-04
Abstract: LD 9843 XENON LAMP PARTICULARLY SUITED FOR AUTOMOTIVE APPLICATIONS ABSTRACT OF THE INVENTION Disclosed is a xenon lamp used for lighting applications and which is particularly suitable for automobile applications such as headlamps. The benefits of such usage, relative to incandescent lamps commonly employed for automotive forward lighting applications along with discharge lamps for lighting application, are primarily related to the size, shape, quality and concentration of the light generated by the xenon lamp and the ability to selectively move the position of the generated light relative to the reflector in which the xenon lamp is housed. The xenon lamp provides for the generation of high intensity light located in front of one of the electrodes of the lamp and is not spread such as along an incandescent filament nor spread between the electrodes as that occurring for other gas discharge devices. The xenon lamp also provides the ability for the light to be generated by excitation of a D.C. source so as to be first positioned relative to the reflector to serve as the light source for low beam applications and then moved to a second position relative to the reflector to serve as the light source for high beam applications. The size and shape of the xenon generated light are respectively smaller and more symmetrical, relative to the light generated by an incandescent source or other discharge devices, and both of these aspects contribute to reducing the size and improving the efficiency of the reflector needed for automotive forward lighting applications. The quality, that is, its color temperature and its color rendition is more advantageous relative to an incandescent light source LD 9843 for automotive applications in that it has an appearance of being more intense. The xenon light source is substantially instantaneously activated and generates light in a manner similar to the incandescent light source which is beneficial for automotive applications.

Abstract: Many  baby  carriers  available  utilize  straps which are adjustable and which use a pair of slip rings through  which  the  strap  is  moved  or,  alternatively, utilize a buckle type adjustment both of which of which are  difficult  to  adjust  particularly  if  the  carrier person has to use one hand to support the baby and the other hand to adjust the straps.   The present carrier uses both ring and snap swivel type adjusters together with  hook  and loop  type  fasteners  such  as  VELCRO?.          Furthermore, the crotch area is padded as are the boun-daries of this area through which the legs of the baby engage.  The crotch is also adjustable in width depending upon the age of the baby and whether or not it is facing to the carrier person or away.  Another advantage is the relatively large pocket formed on the back of the body panel which can be used for carrying small items when the carrier is in use.  However when not in use, the bottom of the pocket is grasped internally and pulled upwardly thus turning the pocket inside out whereupon the straps are folded and placed within the pocket thus enclosing the complete carrier which can then be carried from place to place by means of a small loop handle secured to the upper edge of the pocket.
