Abstract: A parking meter detects an object in proximity, based on a change in a proximity measurement at the meter, activates a directional sensor in response to detecting the object, receives sensor data at a meter processor from the directional sensor, wherein the received sensor data indicates a predetermined direction to the detected object relative to the meter. The parking meter determines a presence of the object, or lack thereof, in the predetermined direction based on the sensor data, and upon a positive determination of the presence of the object, stores an indication of the presence of the object along with a time of the positive determination.

Abstract: System and methods for pre-marshalling messages in an electronic trading environment are provided. Specifically, pre-marshalling messages allows for client and network devices to create messages in response to a defined first condition. Pre-marshalling messages allows a trading system to do more processing up front before the message is needed and when a second condition is satisfied. Thus, when the message is needed no further or very little processing must be performed to generate and send the message. The client and/or network device may allocate a separate, unused, or under-utilized processing thread to the task of creating pre-marshalled messages. Pre-marshalled messages may be stored in memory at the network device until it is determined that the second condition has been satisfied. Once a pre-marshalled message is sent, the unused pre-marshalled messages that were stored in memory may be deleted or may be overwritten with newly pre-marshalled messages.

Abstract: A system and method are provided for modifying how market updates are provided in an electronic trading environment upon detecting one or more triggering events. One example method includes defining an event to be used to trigger modification of how market updates are provided to a client entity, receiving a market update from an electronic exchange, and, when the event is detected, modifying how the market update is provided to the client entity. As an example, the modification of how the market update is provided to the client entity may include providing less data in relation to market updates, and sending the market updates less frequently.

Abstract: A network device coalesces data received from an exchange, and provides a user with the opportunity to receive fewer, but up-to-date, data updates from an exchange when duplicate prices become available or a large volume of prices becomes available suddenly. Accordingly, the trader can be assured of receiving non-duplicated prices that are fed at a rate that is cohesive with that trader's connection speed. The present invention is designed to conserve on bandwidth thereby increasing the likelihood that bandwidth will be available to receive desirable market information.

Abstract: A system and method for displaying quantity related information determined for a plurality of time periods are described. According to one method, a trader may define one or more time periods for which a trading application may determine traded quantities, traded buys, traded sells, or other quantity related information at a plurality of price levels during the defined time periods. The trading application may then graphically display the quantities for each time period in relation to the static axis of prices. The method further includes periodically updating the displayed traded quantity to reflect the quantity during the defined time period, where the quantity is updated based on subsequent market updates that are received from the exchange for the tradable object.
