Title: Stealth virus detection in the chronic fatigue syndrome
Inventor: MARTIN WILLIAM J
IPC: C12Q1/70
Filed: 1992-05-22
Abstract: The present invention relates generally to methods for diagnosing chronic fatigue syndrome and certain other neurological, psychiatric, rheumatological and other stealth virus associated diseases in humans and in animals. Tissue culture and molecular probe based methods for the screening of stealth viral infection are described. The methods are applicable to the diagnosis of stealth virus infection in patients with chronic fatigue syndrome and with various atypical neurological, psychiatric, rheumatological, liver, testicular, salivary gland and other diseases. The methods are also applicable to the detection and the monitoring of naturally infected and experimentally infected animals. Isolates obtained by culture from infected human and animal sources can be used in the development and testing of therapeutic modalities to help in the treatment and prevention of spread of viral infection. The viral detection assays can be applied to the pre-clinical and clinical moinitoring of potential therapy and also to the detection of possible sources of infection, including human to human contact, blood products, domestic pets, farm animals, uncooked foods, vaccines and environmental sources. The isolates can also be used to improve upon the present detection methods, principally through the construction of synthetic antigens based upon the nucleotide sequences of the virus. Antigens produced either synthetically or by recombinant DNA technology, can be used as vaccines to prevent infection and as reagents to monitor immunological responses. A  toxin associated with stealth virus, an antiviral composition comprising the toxin, and methods of monitoring disease state based on detecting the level of toxin or its toxic activity are described.

Title: Oxygen consumption meter
Inventor: MAULT JAMES R
IPC: A61B5/08
Filed: 1991-06-27
Abstract: An indirect calorimeter for calculating the metabolic rate of a subject by measuring the oxygen consumption during respiration over a period of time includes a gas flow meter (42) providing output electric signals to a microprocessor (20) which drives a display and printer. The output of the flow meter (42) is connected to a mouthpiece (12), The exhaled gas passes through a CO2 scrubber (30) and then through the flow meter (42).     The difference in volume be-tween the inhaled gas and the exhaled gas is proportional to the oxygen consumption of the subject and the micropro-cessor (20) integrates that sig-nal over the time of the test, and multiples it by a constant to provide a metabolic rate display. The temperature and water vapor content of the in-haled air are adjusted to that of the exhaled air either by passing both the inhaled and exhaled gases through the scrubber (30) before their volume is measured, or by preheating the inhaled air and employing a water absorbent member to add moisture to the inhaled air and remove it from the exhaled air.

Title: Medical apparatus fixation and infection control device
Inventor: KAY DENNIS
IPC: A61N1/362
Filed: 1992-10-23
Abstract: A device (3) and composition securely affixes an invasive medical apparatus to an entrance site and controls infections associated with the infiltration of microbes along the external walls of such apparatus. Provided in sterile form, the device takes various shapes and sizes and is configured for use with various sizes and types of invasive medical apparatus. The device can incorporate a hydrocolloid composition which, by virtue of its adhesive properties, holds that device in place at a skin entrance site.  Alternatively, fixation is effected by adhesive provided on mating surfaces of the device or by thin-film, adhesive leaves. The device achieves a mechanically occlusive seal, a constant presence of medically active substances such as antiseptics and antibiotics at an apparatus skin entrance site, and a substantially rigid attachment of the apparatus to the area around a penetration site which limits the in-and-out motion and accompanying microbial infiltration common in the use of indwelling invasive medical apparatus.  The device is particularly useful with catheters, cannulae, drainage devices, and pacemaker wires.

Patent CA-2130663-A1 (CA)
Title: Apparatus and method for reducing power consumption in a mobile communications receiver
Inventor: TIEDEMANN EDWARD G JR
IPC: H04B1/16
Filed: 1993-03-04
Abstract: A system for reducing receiver power consumption in communication system having a transmitter and one or more receivers schedules periodic messages in "slots." Each receiver is assigned a slot during which it monitors the transmissions. The transmitter transmits messages to the receiver only during the assigned slots. The receiver is in an "active state" during its assigned slot. It may remain in the active state after its assigned slot if the message requires the receiver to perform additional actions. During the "inactive state," which is the time period between successive occurrences of its assigned slot, the receiver may perform any action not requiring coordination with the transmitter. It may conserve power during this time by removing power from one or more components such as those used for monitoring the transmissions. At a time during the inactive state shortly before the assigned slot, the receiver applies power to these components and performs initializations. Such initializations may include reacquiring a pilot channel signal to which the receiver may synchronize itself if its timing signals have drifted out of synchronization with those of the transmitter during the preceding inactive state.
