Abstract: A joint assembly includes a first member having splines formed therein. A second member includes splines formed thereon and is coupled to the first member. The splines of the first member engage the splines of the second member. An access window is formed on the first member. A ring retains the first member to the second member. A seal extends across a joint between the first member and the second member and covers the access window. A portion of the ring is accessible through the access window following removal of the seal, where the ring can be manipulated to release the first member from the second member.

Abstract: A system for monitoring and controlling a central plant includes a high level optimizer, a subplant monitor, a user interface, and a dispatch graphical user interface (GUI) generator. The central plant includes a plurality of subplants configured to serve a thermal energy load. The high level optimizer is configured to determine recommended subplant loads for each of the plurality of subplants. The subplant monitor is configured to monitor the central plant and identify actual subplant loads for each of the plurality of subplants. The user interface is configured to receive manual subplant loads specified by a user. The dispatch GUI generator is configured to generate a dispatch GUI and present the dispatch GUI via the user interface. The dispatch GUI includes the recommended subplant loads, the actual subplant loads, and the manual subplant loads.

Abstract: An outer joint member for a joint assembly configured to receive an inner joint includes a wall forming a hollow chamber having a closed end and an open end. A plurality of restrictors are coupled to the hollow chamber each having a portion thereof extending outwardly from the inner surface of the wall of the hollow chamber. The plurality of restrictors extending from the inner surface of the wall proximate the open end of the hollow chamber.

Abstract: A state-based control system for an air handling unit (AHU) includes a finite state machine configured to transition between a high cooling load state and a low cooling load state. In the high cooling load state, the system maintains the temperature of a supply airstream provided by the AHU at a fixed setpoint and controls the temperature of a building zone by modulating the speed of a supply air fan. In the low cooling load state, the system operates the supply air fan at a fixed speed and controls the zone temperature by modulating an amount of cooling applied to the supply airstream by one or more cooling stages. A feed-forward module manages disturbances caused by adding or shedding cooling stages by applying a feed-forward gain to the supply air fan setpoint.

Abstract: The application provides a switching circuit for switchably connecting an input node and an output node. The switching circuit comprises a switch operable to switchably connect the input node to the output node in response to a switching signal. A sensor is provided for sensing the voltage between the input and output nodes and providing a sense signal in response thereto. A driver coupled to the sensor adjusts the switching signal in response to the sense signal.

Abstract: A method for dynamically personalizing transportation in a vehicle comprises the steps of providing a vehicle including a messaging device for displaying messages, providing a central dispatch system for managing passenger allocation to the vehicle, receiving passenger specific information at the dispatch system, providing data relating to the passenger specific information from the dispatch system to the messaging device, and selecting and displaying a message based on the data for display. Further, a method is disclosed in which messages depending on passenger specific information, and messages independent form passenger specific information are selected and displayed. The messaging device is in communication with a video display unit or with a printing device for displaying messages received.
