Patent number: 9223002Abstract: A system and a method are provided for determining the position of an underwater vehicle while the vehicle is operating underwater. A buoyant float stays on or near the surface of the water and is attached to the vehicle by thin tether that can include insulated wires. The vehicle moves under the water and pulls the float behind it. The float can receive a localization signal, such as a signal indicating its GPS position, and so can determine its position precisely. The position can be transmitted to the underwater vehicle over the wires located in the tether. The underwater vehicle can use sensors and/or calculations to determine the positional offset of the vehicle from the float buoy and generates its true position based on the known position of the float and the positional offset. The float can be constructed with attributes that will allow the float it operate with a greater tether length, and in turn allow the underwater vehicle to operate at greater depths.Type: GrantFiled: February 15, 2007Date of Patent: December 29, 2015Assignee: Ocean Server Technology, Inc.Inventor: Jonathan C. Crowell

Patent number: 9142971Abstract: Managing electrical power usage in a power distribution system. Power usage data indicative of electrical current flow through electrical outlets in the system are collected and displayed for a user. The user may select an outlet and issue a command to control current flow through that outlet. Environmental data may also be collected and displayed. Outlets in different Cabinet Power Distribution Units (CDUs) in different locations may be clustered for reporting and control. A database structure provides a “system” table for data descriptive of the system, a “tower” table for data descriptive of outlets and other elements in the system, an “infeed” table for data descriptive of input electrical power, and an “outlet” table for data descriptive of electrical power flowing through the outlets.Type: GrantFiled: July 23, 2013Date of Patent: September 22, 2015Assignee: Server Technology, Inc.Inventors: Carrel W.
