Abstract: A mobile floor cleaning robot includes a body defining a forward drive direction, a drive system, a cleaning system, and a controller. The cleaning system includes a pad holder, a reservoir, a sprayer, and a cleaning system. The pad holder has a bottom surface for receiving a cleaning pad. The reservoir holds a volume of fluid, and the sprayer sprays the fluid forward the pad holder. The controller is in communication with the drive and cleaning systems. The controller executes a cleaning routine that includes driving in the forward direction a first distance to a first location, then driving in a reverse drive direction a second distance to a second location. From the second location, the robot sprays fluid in the forward drive direction but rearward the first location. The robot then drives in alternating forward and reverse drive directions while smearing the cleaning pad along the floor surface.

Abstract: In one embodiment, an improved circuit breaker module is installed in an electrical panel of a customer structure that receives power from a solar cell module and a utility company. The circuit breaker module may include a current sensor for sensing electrical current drawn by the customer structure from the utility company. The circuit breaker module may further include a current processing unit for capturing sensed electrical current values to generate energy consumption data and a data transmitter for transmitting energy consumption data to a remotely located data collection computer. The circuit breaker module may transmit energy consumption data over a wired or wireless data link. The circuit breaker module advantageously allows for relatively low cost and easy installation, encouraging installation of solar cell modules even in existing customer structures.

Abstract: Media and gesture recognition apparatus and methods are disclosed. A computerized system views a first printed media using an electronic visual sensor. The system retrieves information corresponding to the viewed printed media from a database. Using the electronic visual sensor, the system views at least a first user gesture relative to at least a portion of the first printed media. The system interprets the gesture as a command, and based at least in part on the first gesture and the retrieved information, the system electronically speaks aloud at least a portion of the retrieved information.

Abstract: The A21 receptor extracelluar site and the A2 receptor extracellular site of adenosine analogues are structurally different and that binding orientations of adenosine or adenosine analogues are different at these sites and this may be used to determine their structure. Novel pyrimidine compounds are described.

Abstract: A self-extinguishing blanket comprises an insulating layer of glass fiber strands which include air spaces within the layer. Each surface of the layer has a bi-directional strand reinforced plastic film which extends continuously along the surface for keeping moisture out of the layer. Each plastic film is attached to the associated surface of the insulation layer by non-contiguous, longitudinally and laterally spaced apart areas of a thermoplastic adhesive. The adhesive areas provide attachment between the strand reinforcement and the layer of glass fiber strands. Each area of adhesive attachment provides sufficient retention to prevent shifting of the film during the sewing together of peripheral edge portions of the sandwiched plastic films and inner insulation layer as required to produce a selected, peripheral configuration of a blanket package.
