摘要： A 3D object is represented by a descriptor, wherein a model of the 3D object is a 3D point cloud. A local support for each point p in the 3D point cloud is located, and reference x, y, and z axes are generated for the local support. A polar grid is applied according to the references x, y, and z axes a along an azimuth and a radial directions on an xy plane centered on the point p such that each patch on the grid is a bin for a 2D histogram, wherein the 2D histogram is a 2D matrix F on the grid and each coefficient of the 2D matrix F corresponds to the patch on the grid. For each grid location (k, l), an elevation value F(k, l) is estimated by interpolating the elevation values of the 3D points within the patches to produce the descriptor for the point p.

摘要： An impedance matching circuit for a radio receives antenna signals and has its matching elements, such as capacitors, progressively switched into the circuit, with the matching element configuration resulting in the highest RSSI being subsequently used until a succeeding test or antenna impedance change. The effect of the matching circuit is accounted for in the transmitter calibration routine so that the matching circuit works for both half duplex and full duplex.

摘要： An automatic channel selection (ACS) process enables an access point to determine a best channel available, i.e., the channel with a least amount of interference, for it operation. When ACS is enabled, the access point scans frequencies for all neighboring access points and their signal strengths. Based on this data, the access point then determines which frequency is least likely to be interfered with by these other access points. The access point switches itself to this frequency and begins operation. During normal operation, the access point may periodically rescan the air space and reevaluate its current operating channel. Preferably, every neighboring access point has its own channel, and the co-channel interference levels should be low enough so that there is a maximum coverage and high throughput for the network. If these characteristics cannot be achieved, the access point may then adjust its power automatically to reduce the interference level in the network. This automatic power adjustment (APA) feature preferably operates across a set of access points, each of which has the function. In this manner, the transmitting power of the neighboring access points in the wireless network is “cooperatively” adjusted to minimize the channel interference and maximize the coverage and throughput for the network. A method of determining optimal access point locations for access points that perform the ACS and APA functions is also described.

摘要： A surgical access device and method are provided for endoscopic surgeries comprising biopsies or other surgical cutting procedures. The device generally comprises a substantially rigid first channel associated with a first port and a second channel associated with a second port of a proximal housing. The first or main channel extends to a curved distal end of the device, and the second channel is connected to a guide channel extending tangential to the main channel. The guide channel comprises substantially noncompliant material and has a pre-insertion position such that a cross-section of an inserted portion of the device is substantially the same as a cross-section of the main channel. A preferred method of the present invention includes the use of an open-loop device formed at a distal tip of an introducer and an aspiration tube during the location, excision and removal of one or more tissue specimens.

摘要： An apparatus for dispensing pressurized material is comprised of a container, a polymeric matrix having a network of macropores located within the container, and a propellant that may be reversibly sorbed with the network of macropores so as to desorb as the partial pressure of the propellant within the container decreases. The network of pores is substantially non-swellable upon sorption and desorption of the propellant during filling and use of the dispensing apparatus. The polymeric matrix may comprise aggregates of macroporous polymeric particles in which the particles define a substantially non-collapsible pore network and the aggregates define interstitial spaces between the particles, and the interstitial spaces are substantially larger than the pore network.
