Abstract: A cleaning system including a motor, a battery receptacle, and a motor controller. The battery receptacle is configured to receive a battery pack. The battery pack includes one or more battery cells and a battery controller. The motor controller is configured to receive from the battery controller at least one selected from the group consisting of a first signal indicative of a first characteristic of the battery pack and a second signal indicative of a second characteristic of the battery pack. The motor controller is further configured to operate the motor at a defined speed, the defined speed being a first speed upon receiving the first signal and a second speed upon receiving the second signal. Wherein the first characteristic and the second characteristic are at least one selected from the group consisting of a capacity, a current, and a resistance.

Abstract: A system and a method are disclosed for organizing content collected in a pen-based computing system. Content collected in the pen-based computing system includes stroke data collected by a smart pen as well as other contextual data collected by the pen-based computing system. The collected stroke data includes timestamps and positional data. Based on correlations of spatial and temporal data, collected stroke data is grouped into clusters of stroke data. The clusters of stroke data, along with contextual data, are further grouped into snippets based on temporal correlations.

Abstract: A system and a method are disclosed for calibrating writing on a writing surface to a digital document. One or more calibration parameters associated with a writing surface and a digital document of a display device are determined. The calibration parameters indicate a spatial offset between a reference position on the writing surface and a reference position in the digital document. A gesture captured by a smart pen is received. The gesture includes a sequence of spatial positions representing movement of the smart pen with respect to the writing surface. The sequence of spatial positions is mapped to a sequence of spatial positions in the digital document based on the calibration parameters.

Abstract: A system and method establishes a connection between a smart pen and a computing device, and establishes a privilege level that regulates data requests for specific data from the smart pen. The smart pen determines whether a connection should be established between the smart pen and a computing device, based on device information received from the computing device. If a connection is established, a privilege level is established for an application executing on the computing device based on the device information, which determines whether a request from the application for specific data from the smart pen is allowed or denied.

Abstract: An improved barrier door one way wireless communication system for operating a barrier, such as a garage door, includes the transmission and reception of multibit code hopping data packets in combination with automatic RF channel switching. Packet data is transmitted automatically on more than one RF channels in a switching style while sending two or more redundant multibit code hopping data packets on each of the RF channels. The system also provides for the learning of a transmitter to a receiver where two or more code hopping data packets must be received and decoded by the receiver on all RF channels before a transmitter can be learned to a receiver. Once the transmitter is learned, actuation of the transmitter during a learn mode can open a window for learning of a single channel transmitter.
