Abstract: A flexible tagging and searching system can be configured to associate tags with the input data to enable a search of the input data. The flexible tagging and searching system can receive user data and determine an identifier associated with the user data. The system can compare the identifier with other identifiers to determine that the identifier is unique. After determining that the identifier is unique, the system can associate a critical tag with the user data and store the critical tag in a database. Then the system can associate a non-critical tag with the user data. In some instances, the system can return query results such as a set of tag data and/or a set of data items.

Abstract: Methods and systems for estimating a location of a wireless electronic device within an environment and linking the presence of the wireless electronic device to a specific set of images collected in the vicinity of the estimated location are presented herein. In one aspect, the physical location of a wireless electronic device at a particular time is estimated based on the strength or time of reception of radio frequency signals collected by three or more geo-locator modules. Each of the three or more geo-locator modules identify a media access control (MAC) address associated with a wireless electronic device. In a further aspect, the geolocation of each identified MAC addressed device is tracked and recorded over time. In another further aspect, the wireless electronic device is linked to images collected by an imaging device while the wireless electronic device remains within a monitored area of the imaging device.

Abstract: A piston drive assembly, including: a housing enclosing each of: a plurality of cylinders, each cylinder having an axis substantially parallel to the axis of the other cylinders; a plurality of pistons, one piston in each cylinder; a wobble plate connected to each of the plurality of pistons; a swashplate rotatably fixed to a drive shaft such that the drive shaft can rotate the swash plate or the swash plate can rotate the drive shaft, wherein the drive shaft extends through the entire length of the housing.

Abstract: A variable displacement piston assembly including a plurality of cylinders, each cylinder having an axis substantially parallel to the axis of the other cylinders, a plurality of pistons, one piston in each cylinder, and each piston and corresponding cylinder having a displacement. The assembly also including a transition arm having a connector pin for each piston, each connector pin connecting each piston to said transition arm, a drive shaft connected to the transition arm and a control shaft rotatably coupled to the drive shaft, the control shaft being movable to adjust the displacement of the piston assembly.

Abstract: A bowling scoring system having a graphic user interface includes an input selection device for receiving user input selections. The bowling scoring system is responsive to a pin-fall sensor to compute bowlers' scores which are displayed to provide information to the bowler. The system includes a controller program having various program states for performing a particular one of a plurality of functions. A plurality of input selection keys juxtaposed with the display device to provide input to the controller. Softkey indicia areas on the display device are associated with one of its input selection keys. The controller is responsive to the state of the program for displaying a particular label in at least one of the indicia areas and for performing a function associated with the displayed label in response to actuation of the one of the input selection keys associated with the labeled indidia area.
