Abstract: An electronic interval timer in a dodecahedron case is described. The timer is set by turning uppermost one of 11 faces; and reset by turning uppermost the 12th face. In one embodiment, the timer is free of buttons, knobs, springs, time displays, electronic visual indicators and openings in the case. Time interval completion is announced via audible tones or speech. An aggregate time interval may be set equal to the sum of legends on more than one face. The timer detects carrying such that a running time interval is not modified. The timer may be programmed via a sequence of uppermost sides. Modes may be selected via shaking or tapping. Time remaining may be announced, an interval cleared, or an interval restarted responsive to detected motion. Other polyhedral shapes may be used. Claims include a method of setting a time interval; and specific ordering of face legends.

Abstract: An enclosed chamber is used in a system for screening of a liquid specimen through binding assays. The enclosed chamber includes an inlet, an outlet, and a plurality of discrete reactant containing wells communicated by a common reagent flow path between the inlet and the outlet. A transparent member or coverslip defines on an inside thereof the plurality of wells. Each well has a bottom for receiving an allergent/antigen/reactant, which emits light upon reacting. The coverslip can optionally define at least one lens at each well. A bottom encloses the plurality of wells and defines between the inlet and the outlet a common reagent flow path between the inlet and the outlet. This bottom defines for each of the plurality of wells a flow-diverting member. An opaque partition is disclosed for surrounding the individual lenses and generally isolating the light path from each well.

Abstract: The present invention relates generally to the field of healthcare. Particularly, in the remote monitoring and modulation of a medical device on or in a subject. The present invention provides both systems and methods for remote monitoring of a subject, as well remote treatment of a subject (e.g. modulation of a medical device).

Abstract: An apparatus and method for cleaning containers, such as sample containers for environmental testing, involves providing fluidly isolated modular cleaning bays which are interchangeably cascaded together for processing trays of containers through different washing and rinsing solutions. In each modular bay a bank of nozzle elements is cycled to traverse into and out of the tray of containers to clean the interior surfaces of the containers.

Abstract: An apparatus and method for cleaning containers, such as sample containers for environmental testing, involves providing modular cleaning bays into which an array of inverted containers can be transported, such as by means of a drive chain. Independently operable nozzle banks disposed in the cleaning bay generally below the resident container tray are driven in an x-axis motion, such as by a stepper motor, to register a selected nozzle bank with successive rows of containers within the tray. At each row of containers the nozzle bank, which is selected in accordance with the size and spacing of the containers being processed, is caused to travel in a z-axis motion through a process cycle in which the nozzle elements of the nozzle bank traverse through the open mouth ends of the containers registered therewith and in which a fluid stream is projected directly onto the interior surfaces of the containers, preferably sweeping the entirety of those surfaces.

Abstract: An auto-changer for optical discs. At least one carousel rotatable about a horizontal axis stores a large number of discs. A picker moves into the carousel to grasp a disc in a horizontal position in the carousel and then move the disc to a position outside of the carousel. A transfer arm grabs the disc from the picker and swings the disc in an arcuate path over to a disc player, where it is deposited for playing.

Abstract: Method and apparatus for use in the diagnostic analysis of a liquid specimen through binding assays. The apparatus includes a rigid body having an elongated, shallow well formed in it, with a plurality of elongated strips, preferably in the form of cotton threads, stretched across the well in spaced relationship and generally perpendicular to the well's longitudinal axis. Each thread is coated with a separate binding conjugate such as an antigen or allergen. A cover plate that includes a thin plastic layer and an overlaying thin metallic layer covers the well to form an enclosed chamber having a specific volume. The metallic layer includes a separate elongated aperture in alignment with each coated thread. A liquid specimen is introduced into the chamber through one of two ports, for incubation with the coated threads, after which the specimen is removed and the reaction that occurred on each thread is determined.

Abstract: A portable photo chamber for photographically recording the extent of a chemical reaction such as in an immunological test, wherein a substrate emitting radiation such as gamma radiation is supported in facing contact with a film and with intensifying means, so that exposure time is reduced as a result of emission of further radiation such as a visible light from the intensifying means and its recording on the film. The photo chamber includes retaining means for supporting the substrate, which itself is preferably enclosed in a container such as a pipette, and translating means for moving the substrate into closely facing relationship to the film and also to a spaced-apart position within the chamber. In a preferred embodiment, the photo chamber utilizes an instant photographic system with film processing means attached to the chamber, so that the photo chamber is both portable and self-contained for use in remote locations.
