Abstract: An inventive channel marker includes a least a buoyant member, a display device, a photovoltaic cell and power storage assembly, and a display device connected to a wireless communication system. The inventive channel marker may also be inflatable. Accordingly, the inventive channel marker facilitates its deployment as a temporary channel marker that can be easily stowed when not in use, and with a display that can be configured on the fly to present any desired information.

Abstract: Systems and methods for a filtering wave energy using a rectangular-to-circular waveguide transition are discussed herein. An exemplary system comprises a rectangular-to-circular waveguide transition and a filter card. The rectangular-to-circular waveguide transition may include a front section and a back section opposite the front section, the rectangular-to-circular waveguide transition defining a circular hole extending from the front section of the rectangular-to-circular waveguide transition through the back section, the rectangular-to-circular waveguide transition further having a first arcuate region on the face of the transition, the first arcuate region defining a first cavity extending from the circular hole through the first arcuate region, the rectangular-to-circular waveguide transition also having a second arcuate region defining a second cavity opposite the first cavity, the second cavity extending from the circular hole through the second arcuate region.

Abstract: Waveguide flanges for joining waveguide sections or components are designed to achieve mechanical strength and exhibit desired electrical properties such as relatively low insertion loss and high return loss. The present invention contemplates waveguide interfaces with a new choke flange designed to engage with a shield flange and provide a joint with improved electrical properties. The new choke designs produce a virtual continuity through the waveguide joints and minimize electrical energy leakage. The electrical and mechanical properties of the joint in the waveguide interfaces are robust and able to tolerate lower levels of parts precision, imperfect mating of the flanges without metal-to-metal contact and gaps up to 0.06? or more between the mating flange surfaces.

Abstract: A method and apparatus for improving the performance of Building Environmental Control networks by efficiently storing network routing information and by checking that the data exchanged between two computer applications operating on the network is consistent. The present invention efficiently stores network routing information by having the Building Environmental control network routers only store routing information when that router acts as a bridge for communicating that message further downstream. The present invention also checks that the exchange of data between two building environmental control applications is done by forming a special identifier from the existing data and using that identifier to validate data exchanges. The special identifier is formed by segmenting one field found within the data and having a portion of that segmented field be indicative of the identifying name of the data.

Abstract: A method for determining the physical locations of devices located on a series connected network. A mapper routine located on the network severs a device from the network and then requests each device to respond with its respective node address to the mapper. Upon receiving the responses, the severed device is reattached to the network. This severing, requesting, and reattaching is performed for each remaining device on the network. The mapper routine determines the physical location of each device by correlating what responses from the devices were generated for which severed devices.
