Abstract: A headset for detecting brain electrical activity is disclosed. The headset may have a flexible band having a first end and a second end. The flexible band may have at least one expansible region permitting a distance between the first end and the second end to selectably vary. The headset may also have flexible circuitry in the flexible band. The flexible circuitry may be operatively connected to at least one sensor configured to sense brain electrical activity. The headset may further have a stimulus emitter coupled to the flexible band.

Abstract: The present invention provides fluid and material delivery methods and devices for practicing the methods. The invention provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection. The method comprises the steps of aspirating the cellular material into a fluid delivery device which incorporates a syringe arrangement. The cellular material is aspirated into the main body of the syringe until the desired amount of a material has filled the syringe body. The needle of the fluid delivery device is then inserted into the skin of a subject at an angle about parallel to the skin until a desired depth has been reached. The cellular material is then injected in the subject until the desired volume of material has been injected. The needle of the device is then rotated approximately 45 to 90 degrees and the needle is removed from the injection site.

Abstract: A movable barrier operator includes an absolute position detector which provides a unique value for each position of the barrier along its path of travel. The absolute position detector employs multiple binary serial streams and one multiple clock stream. After the first five cycles of the clock stream, the binary streams can be decoded by a processor to produce an absolute position. Every clock edge produces a new absolute position along the path of travel.

Abstract: A method of programming a controller for a movable barrier operator includes enabling and disabling an input device within a predetermined period of time, a predetermined number of times. This sequence of short activations of an input device, such as a switch on a wall unit, puts the controller in a learn mode or a programmed state. Thereafter, the controller is responsive to learn any of the various routines that can be programmed for the movable barrier operator, such as transmitter code, limits of travel, force settings, and so on.

Abstract: The invention is an automated sprayer for spraying the walls of a bath and shower enclosure with a cleanser. The sprayer has a housing that can be mounted inside the shower enclosure and that defines a tray in which an inverted bottle of cleanser is stored. The bottom of the tray has a tube extending downwardly along a longitudinal axis through which the cleanser can pass. A motorized head disposed beneath the tube can be rotated about the axis for metering cleanser from the bottle and spraying cleanser outward. The sprayer includes timer circuitry that delays commencement of a spray for a set time and automatically stops spraying after a predetermined period. The sprayer also includes a system for signaling the beginning of a spray cycle including audio and visual alarms. An automated method of cleaning the shower enclosure is also disclosed.

Abstract: An operator for opening and closing movable barriers such as garage doors comprising a pass-point limit system which is a component of an operating head. An operator for a rolling shutter or gate can be installed on either side of the opening. A dual pass-point system provides a unique pass-point regardless of direction of mounting the operator, regardless of the direction of travel for opening the barrier, and regardless of installation configuration, eliminating the need for the installer to know which direction the motor is rotating or the barrier is travelling.

A dual pass-point system provides a unique pass-point regardless of direction of mounting the operator, regardless of the direction of travel for opening the barrier, and regardless of installation configuration, eliminating the need for the installer to know which direction the motor is rotating or the barrier is travelling. The operator automatically learns both the open and close limits, regardless of direction of travel and without having to press a learn switch to set the open and close limits.
