Abstract: A controller is provided to control movement of a plurality of transporting devices. In particular, the controller provides improved robot shunting. More specifically, the controller delays the planning of a shunt path for an idle robot until closer to the time the idle robot needs to move out of the way. Advantageously this avoids the computing burden of planning shunts in advance that are never performed because the idle robot is subsequently tasked before the shunt were due to start. In particular, shunt paths can be planned very close to the time at which they need to be executed thereby providing a more efficient solution to robot shunting because very close to the execution time there is a very small probability that the plan will change in a way that the shunt needs to be recalculated.

Abstract: Currently, a user may need to carry or otherwise keep track of both a mouse and electronic pen for a computer, such as a portable computing device. Carrying or otherwise keeping track of both devices can be tedious. Accordingly, systems and methods for providing a dual mode mouse pen are enabled, whereby the mouse pen may be used as both a pen, or alternatively, as a mouse. In one embodiment, the pen may include a switch to select one of two modes: pen or mouse.

Storage is provided inside the input device for a variety of types of data files other than for storing positional information and a corresponding storage access mode is provided to read, write or render from the storage, so that the input device may store, transmit, receive and otherwise operate upon data, such as music, files, pictures, etc., while also having an input mode that relates to the ordinary operation of the pen or stylus, either active or passive.

Abstract: An optical cursor control device, for example, an optical mouse, is adapted to use its array sensor to capture image intensity data associated with barcodes. The image intensity data and associated x-y position data is processed to recreate the barcode image and then is decoded to deliver data to a process running on an associated computer. An apparatus and method are disclosed as well as alternatives to reduce the amount of data sent between the cursor control device and the computer.

Abstract: A method, apparatus, and system for tracking movement of a device are described. The method includes steps of implementing a first tracking subsystem for tracking positions of a device against a surface, determining whether to implement a second tracking subsystem for tracking positions of the device against the surface, capturing data corresponding to a location on the surface, and determining a position of the device against the surface based on the captured data. The position of the device can then be transmitted to a host computer and used in an application program. The first and second tracking subsystems may be a relative and an absolute tracking subsystem respectively.

Abstract: A method of waste stabilization by mineralization of waste material in situ in a treatment container suitable or treatment, transit, storage and disposal. The waste material may be mixed with mineralizing additives and, optionally, reducing additives, in the treatment container or in a separate mixing vessel. The mixture is then subjected to heat in the treatment container to heat-activate mineralization of the mixture and form a stable, mineralized, monolithic solid. This stabilized mass may then be transported in the same treatment container for storage and disposal.

Abstract: Pixels in an array of image sensor pixels contain photo-sensors. In response to illumination of a photo-sensor, an initial signal is generated. Multiple comparison signals are also generated based on the initial signal. One of the comparison signals remains internal to the pixel, and other comparison signals are transmitted to neighboring pixels. Within a pixel, the internal comparison signal is compared to a sum of comparison signals received from neighboring pixels. Based on the comparison, a data value may be latched and used for indicating a relative difference in pixel illumination.
