Abstract: A system useable in a jet aircraft having installed therein a pressurized oxygen supply which feeds oxygen into the interior of the plane when it flies at high cabin altitudes, the system indicating the changing status of the supply as oxygen is drained therefrom. The system includes a pressure transducer coupled to the supply and means associated with the transducer to determine the lapse rate at which the pressure of the supply is reduced as oxygen is drained therefrom to yield a first signal representing this pressure lapse rate, and to concurrently determine the lapse rate at which the number of liters of oxygen in the supply is reduced as oxygen is drained therefrom to yield a second signal representing the liter lapse rate. These signals are applied to a microprocessor in whose data base is entered the total oxygen inventory of the supply and the oxygen demand of the plane in which the supply is installed.

Abstract: A chair ergonomically designed to cause its occupant to assume a sitting posture that acts to distribute the load imposed by the sitter's upper body weight so as to relieve stress on the musculature of the lower back, thereby obviating lower back pain. The seat of the chair is slidable along a track that is upwardly inclined at a fixed angle relative to the structure on which the chair is supported. Hinged to the seat is a backrest that is supported at the rear of the chair. When an individual sits down to place his buttocks on the seat, he then slides the seat along the track until the backrest assumes an angle with respect to the seat at which it is comfortable to the sitter, and the seat is then latched to maintain this orientation.

Abstract: A multiple dog leash which makes it possible for a single individual to concurrently control at least two dogs that differ in size and therefore require leashes of different length. The multiple leash includes an elongated strap that passes through a coupling ring and is folded thereover to define two leash sections whose relative lengths depends on the site of the fold; a leash handle being linked to the coupling ring. Each leash section terminates in a connector that can be coupled to the collar or harness of a dog. Slidable along the two leash sections is a sleeve that acts to maintain these sections in parallel relation. Also slidable on the two sections between the sleeve and the connectors is a lockable clamp which after the strap is adjusted to create two leash sections having relative lengths appropriate to the dogs to which these sections are coupled, is then locked to maintain this relationship.

Abstract: A readily movable cafe chair that is multi-functional and therefore useable by its seated occupant in various ways. The chair includes a back section formed by a sculptured panel defining a flat figure whose head merges with a body region having outwardly swelling hips from which extend widely spaced legs between which is a crotch zone. Joined to the back section is a front section having a lobe-shaped seat whose front end is supported by a pair of front legs which are spaced from the rear legs and are coupled thereto by a fork. The arcuate rear end of the seat is attached at its apex to the crotch zone of the back section. The sides of the lobe-shaped seat curve inwardly toward the crotch zone to create free spaces adjacent the rear legs of the chair. Thus the occupant may seat himself in a direct mode facing forwardly, or in a reverse mode facing rearwardly. The occupant when seated with his back against the back section can safely back-tilt the chair.

Abstract: A wet electrostatic scrubber unit for extracting from a polluted air stream particulate matter entrained therein, whereby emerging from the unit is an environmentally acceptable air stream. The unit includes a treatment station having a cylindrical duct through which is blown the polluted air stream. Coaxially disposed within the duct is a water delivery pipe having nozzles along its length from each of which is projected a radial beam of water. The radial beam collides with the inner surface of the duct to create a turbulent mist which is intercepted by the polluted air stream flowing through the duct. The velocity of the radial beam is such as to cause it to collide with the duct surface with sufficient force to triboelectrically generate negative ions. These cause the mist to acquire an electrostatic charge to capture the contaminates entrained in the polluted air stream. The negative ions also react with oxygen in the air stream to produce ozone that oxidizes the particulate matter captured by the mist.

Abstract: A baffle mountable on the tube of a fluorescent lamp which in the absence of the baffle yields a harsh and glaring light. The baffle is formed of a long strip of fabric material having a row of holes therein through which the tube is threaded to cause the strip to assume the shape of an undulating shade which conceals the lamp. The felt strip is preferably constituted by a pressed, non-woven felt fabric whose fibers are reflective of light and absorbent of sound or a similar flexible absorptive material. Light rays emitted by the lamp are intercepted and dispersed by the shade, thereby diffusing the light and softening the illumination. Ambient sounds impinging on the undulating shade are absorbed thereby to reduce the noise in the room in which the lamp is installed.

Abstract: A rudder for a sailboat or other vessel formed by a lightweight core having the combined shape of the blade and the stock of the rudder, and a fiber-reinforced resin skin enveloping the core and conforming thereto to create a monocoque structure in which the skin bears the major portion of the torsional and bending stresses to which the rudder is subjected when in use. The pre-cast foam-plastic core of the rudder is formed by a blade section and a stock section having a root received in a slot in the blade section, the stock section being wrapped with a layer of reinforcing fibers before being combined with the blade section. To produce the rudder, the pre-cast core is placed in the cavity of a mold lined with reinforcing fibers which wrap the core inserted therein.

Abstract: An electronic stimulation system for treating a patient suffering from a tinnitus disorder in which the patient hears ringing or other sounds originating in the ear. The system includes an electrodynamically-actuated diaphragm and probe assembly acting as an applicator to which is applied a complex signal in the sonic range to cause the probe to vibrate in accordance with the signal and the diaphragm to audibly reproduce the signal. The probe is placed at a site on the patient in proximity to the cochlea of the inner ear whereby the probe vibrations are transmitted to the cochlea to stimulate this organ and thereby alleviate the tinnitus disorder. Because the patient who hears the internally-generated tinnitus sounds, also hears the reproduced complex signal he is able to adjust the generator of the complex signal so that its frequency components act to mask the frequencies of the tinnitus sounds.

Abstract: The invention is directed to a method of evaluating the signal of an infrared thermometer for measuring human body temperature, in which the infrared thermometer includes a probe adapted to receive thereon a probe cover or protective film sufficiently transparent to infrared radiation, and in which on a measuring operation performed with the probe cover or protective film in “installed” condition the signal is evaluated, so that a measuring operation is performed also when the probe cover or protective film is not installed, with an appropriate allowance being made for the consequently more intensive infrared radiation by different signal evaluation.

Abstract: A system and method for detecting and thus preventing check fraud utilizing a digital computer with image capture and interpretation systems. The system converts the payee information, issue date and the MICR line information (account number, check number and dollar amount) to a check digit which is then placed into the MICR line of a check, printed on its face or transmitted via the paid issuance file to the drawee bank. The drawee bank, upon presentment utilizes a transformation algorithm to convert the printed payee information and issue date on the check into a numerical value that is combined with MICR line information and a check digit is calculated based upon pre-agreed logic. This unique data processing system quickly confirms properly presented checks while effectively precludes payee and other alterations in a cost effective manner.

Abstract: An integrated laser/modulator (“ILM”) operating with reduced chirping is formed on a single semiconductor substrate. A reduction in chirping and any resultant wavelength dispersion is realized by precisely controlling the length of a window region incorporated in the ILM in order to isolate the ILM's active regions from any residual reflections.
