Abstract: In one embodiment, a miniaturized structure and associated method function as a mass spectrometer or analyzer and may, with modification, function as an ion generator. The miniaturized structure has a pair of generally planar parallel spaced electrodes which have projecting walls cooperating to define an ion generating chamber and an exit aperture. By controlling the electric field which is oriented perpendicular to an applied magnetic field, the ion beam may be separated into a plurality beams based upon mass to charge ratio with a predetermined mass to charge ratio emerging from the exit of the apparatus and when the apparatus is functioning as a mass spectrometer or analyzer impinges on an ion collector which responsively transmits information to a cooperating processor. Where it is desired to have it function as an ionizer the ion collector disposed adjacent the ion exit is eliminated.

Abstract: A drain cleaning apparatus has a remotely adjustable cable feed control. The drain cleaning apparatus includes a rotatable cable drum that carries a drain cleaning cable. Also included is a cable advancing mechanism. The cable is adapted to pass from the cable drum and through the cable advancing mechanism. The cable is also adapted to rotate about its feed or longitudinal axis when the cable drum is rotated. The cable advancing mechanism includes a plurality of rollers for engaging the cable. The rollers are selectively adjustable among a cable displacing position and a neutral position. A guide conduit assembly is coupled to the cable advancing mechanism. The rollers may be selectively adjusted between the cable displacing and the neutral positions by an operator remotely rotating the guide conduit.

Abstract: A system for detecting, monitoring and reporting physiological information includes a sensor device adapted to be worn on the upper arm that includes at least one of an accelerometer, a GSR sensor and a heat flux sensor and generates data indicative of at least one of activity, galvanic skin response and heat flow. The sensor device may also generate derived data from at least a portion of the data indicative of at least one of activity, galvanic skin response and heat flow. The system includes a central monitoring unit that generates analytical status data from at least one of the data indicative of at least one of activity, galvanic skin response and heat flow, the derived data, and previously generated analytical status data, a means for establishing electronic communication between the sensor device and the central monitoring unit, and a means for transmitting data to a recipient.

Abstract: A drain cleaning machine includes a housing and a cage member that is axially displaceable along and rotatable about the longitudinal axis of the housing. The cage member has an axial bore and is adapted to receive a cable. A plurality of jaw elements are inserted into and displaceable within the cage member. A rotatable cone member surrounds the first end of the cage member and is adapted to engage the jaw elements and displace the jaw elements radially inward within the cage member as it is axially displaced along the longitudinal axis. A motor is coupled to the cone member for rotating the cone member, wherein rotation of the cone member causes rotation of the cage member. The jaw elements are adapted to engage and grip the cable such that rotation of the cage member causes rotation of the cable about the longitudinal axis.

Abstract: A sensor array and computing apparatus are located on the human body while maintaining said sensors and apparatus within a proximity zone of the body such that the mobility and flexibility of the body are not deleteriously affected by the presence of the apparatus. A series of rigid and flexible pods within which the sensors and computing apparatus may be housed are typically comprised of a rigid material having a minimum hardness or rigidity mounted in conjunction with certain more flexible sections to allow relative movement of the rigid material sections with respect to each other. The flexible material is further utilized to conform said rigid sections to certain pre-specified portions of the human body. The system permits the dynamic monitoring of human physiological status data without substantial interference in human motion and flexibility.

Abstract: A computer based package delivery and control system for tracking receipt and internal delivery of items such as packages. The system maintains a database of records of information relating to packages which have been received by an organization at a facility such as a mail room. The records include the names of employees who are the ultimate recipients of the packages as well as the internal delivery status of the packages. The system is also provided with a programmable, portable data terminal which has a capability for the input of graphical data and includes an integral bar code scanner. The portable data terminal may be used to input package information to the data processing system when packages are received. From time to time, the data processing system downloads internal delivery manifests to the portable data terminal, which may then be used to deliver packages to the employees who are the intended recipients.
