Abstract: Methods and apparatus which allow a wireless terminal (302) to simultaneously maintain connections with multiple base stations (304, 306) are described.  Each wireless terminal (302) is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (302, 306). In this manner base stations (302, 306) receive different data allowing for asynchronous data transmission. The data received by the base stations (302, 306) can be supplied to a wired asynchronous network (308) without the need to combine the received data prior to supplying it to the wired network (308). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

Title: Method of detection of signals using an adaptive antenna in a peer-to-peer network
Inventor: PROCTOR JAMES A JR
IPC: H01Q3/26
Filed: 2002-09-12
Abstract: An adaptive antenna signal identification process to provide increased interference rejection in a wireless data network such as a wireless Local Area Network (LAN) (11-1, 11-2), The adaptive antenna (20-1, 20-2)is located at an access point (14-1, 14-2) and can be steered to various angle of arrival orientations with respect to received signals. Associated radio receiving equipment utilizes two distinct signal detection modes. In a first mode, the directional antenna array is set to have an omni-directional gain pattern. When the invention is deployed in a relay function, where messages received from a first node (12-1-1, 12-2-2, 12-1-n) are to be forwarded to a second node (12-2-p), the recorded direction of its best reception is retrieved for the second node (12-2-p) and used when the antenna array (20-1, 20-2)is used to transmit the signal to the second node (12-2-p). Storage of the best antenna angle for propagation to neighbor nodes can be handled by control functions in a manner that is analogous to other router lookup tables, such as being contained in a lookup table (25) that stores IP addresses.

IPC: C12N5/04
Filed: 2004-06-17
Abstract: A method and system for automatically harvesting and screening plant embryos in multiple stages to identify those embryos that are suited fox incorporation into manufactured seeds are provided. The method includes generally three steps. First, plant embryos are automatically sorted according to their rough size/shape and also singulated into discrete embryo units, for example by vibrational sieving. Second, the sorted and singulated plant embryos are classified using a first classification method. For example, each embryo may be imaged by a camera and the image is used to ascertain the embryo's more precise size/shape. Third, for those embryos that have passed the first classification method, a second classification method is applied. F or example, a pre- developed classification algorithm to classify embryos according to their putative germination vigor may be applied to the same image used in the first classification method, to identify those embryos that are likely to germinate.

Title: Packaged virus-like particles for use as adjuvants: method of preparation and use
Inventor: BACHMAN MARTIN F
IPC: C07K14/02
Filed: 2003-06-20
Abstract: The invention relates to the finding that virus like particles (VLPs) can be loaded and packaged, respectively, with DNA oligonucleotides rich in non~ methylated C and G (CpGs). If such CpG-VLPs are mixed with antigens, the immunogenicity of these antigens are dramatically enhanced. In addition, the T cell responses against the antigens are especially directed to the Thl type. Surprisingly, no covalent linkage of the antigen to the VLP is required; it is sufficient to simply mix the VLPs with the adjuvants for co-administration. In addition, it was found that VLPs did not enhance immune responses unless the y were loaded and packaged, respectively, with CpGs. Antigens mixed with CpG- packaged VLPs may therefore be ideal vaccines for prophylactic or therapeuti c vaccination against allergies, tumors and other self- molecules and chronic viral diseases.
