Abstract: A mobile thermal regulation facility is a trailer mounted container defining a thermally regulated interior space in which people may walk, stand and sit. One or more doors are provided for ingress and egress. An exhaust fan may maintain a negative pressure space between paired doors to help maximize energy efficiency. Seating is provided. Electric and data utilities in the form of one or more outlets, USB charging stations, an internet access points (e.g., WiFi) may also be provided. Other accoutrements may include display screens for displaying television programming or video captured events.

Abstract: An axillary airfoil located as far forward as practicable on the fuselage of an airliner. During high speed cruise, the airfoil can be adjusted to provide supplemental lift to move the center of pressure forward, thereby reducing the amount of downforce needed to be produced by the vertical stabilizer. This would result in saving fuel. Spoilers mounted on the airfoils would be programmed to automatically deploy to return the center of pressure rearward whenever flight conditions require greater longitudinal stability.

Abstract: A payee (a vendor) creates bill 46 with account information 14 and activity 22 printed in alphanumeric characters and in a barcode symbol 42. Bill 46 is sent in the mail to a payer (a customer). The payer scans symbol 42 into a PC 52 (personal computer). Scanning wand 48 decodes symbol 42 and transmits it to PC 52. An editor 54 is installed on PC 52. Editor 54 interprets signals and displays interactive visual image 60 on a display terminal 62. The payer verifies that the information on image 60 is the same as on bill 46. The payer clicks the next button with a mouse 66 to show a transaction display 68 on terminal 62. The payer determines that he or she wishes to pay amount 73 and enters amount 73 on display 68. The payer instructs editor 54 to transfer a payment order 82 either to an electric banking software program 58 installed on PC 52 or to an online program 59 accessible through a modem 55 of PC 52.

Abstract: A half bridge driver chip for driving a resonant load, such as a ballast, has first and second pairs to which an oscillation frequency timing circuit, matched to the resonant frequency of the load. A constant voltage drop circuit is connected to these input pins to vary the voltage at the pins as a linear function of the input voltage V.sub.cc. Consequently, when V.sub.cc is increasing during the start-up of the circuit, the resonant frequency is initially high but decreases to its operation value as V.sub.cc increases. This produces a soft start characteristic and a timed preheat cycle of the resonant load. In one embodiment, the constant voltage drop circuit is a zener diode; in another embodiment, it is strings of anti-parallel connected diodes.

Abstract: A safety shower adapted for reliable operation under all weather conditions is provided with strategically located bleed means for draining water from the shower, at least one of such bleed means including a temperature sensitive valve which permits limited flow of supply water upon the occurrence of predetermined ambient temperature conditions.In temperature zones the temperature sensitive valve will be one responsive to near freezing temperatures, in equatorial zones the temperature sensitive valve will be one responsive to dangerously high water temperatures, and in intermediate and temperate zones both types of temperature sensitive valves may be employed.Other bleed means is preferably employed to facilitate draining of water from portions of piping beyond the shower activating means when the shower is not in use.
