    摘要： An energy harvesting device, system and method are described. The energy harvester collects acoustic energy and transforms it into electrical energy for use by a sensor. The energy harvester utilizes a piezoelectric device, which may be encased, either wholly or partially, within an acoustic chamber. Alternatively, the piezoelectric device may be entirely exterior to the acoustic chamber, which acts to amplify the collected acoustic energy.

    摘要： A technique is provided for utilizing a computer system to generate tool paths for the computed aided machining (CAM) in at least four axis of a selected workpiece or part, particularly a complex part having hidden surfaces. The technique involves storing in the computer system both a surface point representation of a workpiece, which representation contains a unique code for each surface point, and a representation of the tool for which the paths are to be generated. The workpiece surface is viewed from a discrete number of orientations and a map of surface points visible from each of the orientations is generated. The map is then used to obtain selected most promising access directions for access to voxels in the delta volume to be removed or for access to surface points for a finishing operation. Such most promising access directions may for example be obtained by thinning an access cone for the voxel/point. Collision detection is then performed for the tool along each of the most promising access directions and the directions adjusted to eliminate collisions, resulting in a legal direction for each voxel/point. The legal directions are then connected into the tool paths, with collision detection preferably being performed on the tool paths and the tool paths adjusted to avoid detected collisions. Tool paths may be individually generated for successive slices of the delta volume. The tool paths generated may be stored on a machine readable medium.

    摘要： Methods and apparatus for use in communicating messages to multiple recipients are described. A wireless device receives a first input request for creating a new message, and also receives one or more second input requests for selecting a plurality of recipient identifiers for the new message. The wireless device also receives a third input request which indicates whether or not the message is for a group conversation. When the third input request indicates group conversation, the wireless device formats the recipient identifiers in first header fields (e.g., CC header fields) of an MMS message. When the third input request indicates no group conversation, the wireless device alternatively formats the recipient identifiers in second header fields (e.g., BCC header fields) of the MMS message. The MMS message is then transmitted to the recipient identifiers via a wireless network. Recipient devices may process the message as group or non-group (e.g., broadcast) depending on the field locations of the recipient identifiers.
