Abstract: A service for storing time series data provides a data pipe for receiving time series data, a query pipe for making requests to the service, and a result pipe for receiving output from the service. Data sent to the query pipe is processed by an ingester that prepares metadata indices associated with blocks of incoming time series data and stores the blocks of data in a time series database and the indices in a separate index database. A query layer receives queries from the query pipe and uses the index database to determine which data blocks are needed to process the query, and then requests only those data blocks from the time series database. Processing of the query is performed within the time series database only on those data nodes that contain relevant data, and partial results are passed to an output layer for formation into a final query result which is sent out by the results pipe.

Abstract: A method for performing queries on a distributed time series data storage system is presented. The time series data storage system has a time series database that stores data blocks containing time stamped data across a plurality of computing devices. The system also includes an index database that stores an index associated with the time stamped data in each data block. The method includes the steps of sending a query, requesting indices, returning the indices, preparing a sub-query, forwarding the sub-query to an evaluator, evaluating the sub-query, performing a logical operation on each sub-query's result, receiving the sub-results at an output handler, and combining the sub-results.

Abstract: A system for storing time series data includes an ingester that prepares metadata indices associated with blocks of incoming time series data and stores the blocks of data in a time series database and the indices in a separate index database. The time series database distributes storage of the data blocks among multiple data nodes. A query layer receives queries and uses the index database to determine which data blocks are needed to process the query, and then requests only those data blocks from the time series database. Processing of the query is performed within the time series database only on those data nodes that contain relevant data, and partial results are passed to an output layer for formation into a final query result.

Abstract: An LED-based lighting unit for retrofitting a fluorescent light fixture in a transit vehicle has a concave frame or structure conforming to the shape of the fluorescent lighting fixture cavity, connector pins on either end of the frame for secure attachment to sockets of the fluorescent fixture, a plurality of LED modules for illuminating an area of a transit vehicle, a power adapter for receiving and converting an input power supply signal, and a diffusive lens cover. The frame may have rear fins or other features for facilitating dissipation of heat generated by the LEDs. A controller adjusts the intensity of the LEDs based on a reading from a temperature sensor and on a manual brightness setting. The change in light output may be accomplished by reducing a duty cycle of a pulse width modulated (PWM) waveform supplying the LEDs.

Abstract: A vehicle control and display system to control the vehicle systems and display vehicle information. A control processing unit communicates with remote units and the vehicle systems wherein when the control processing unit receives commands from the remote units, the control processing unit transfers these commands to the vehicle systems. The vehicle information is displayed on the control processing unit or on the remote units. The control processing unit receives vehicle information from the vehicle systems and transfers that information to remote units to be displayed.

Abstract: A vehicle headlight and control system for a bus or large vehicle includes a headlight fixture with a center or low beam light source and side illumination light source operated independently. The side illumination light source may be activated when the vehicle is turning, as detected by the vehicle speed and steering shaft turn angle, to provide supplemental illumination. Both right and left side illumination sources may be provided, and may comprise LED light elements. The system may also include an audible sound generator to alert pedestrians when the vehicle is turning.

Abstract: A cylinder device is retained in a retaining space of a pneumatic tool, and includes first and second end components, a surrounding wall coupled between the first and second end components and dividing the retaining space into an annular space part and an inner space part, and a pair of main dividing members dividing the annular space part into an intake space region and an discharge space region. Compressed air introduced into the intake space region enters the inner space part via an inlet hole formed in the surrounding wall to drive rotation of a rotor disposed in the inner space part, and is advanced into the discharge space region via outlet holes formed in the surrounding wall to be expelled to the external environment.

The seat has multiple chambers, each of which has two opposite sidewalls, a bottom, two through holes and an opening. The two through holes are respectively defined on the sidewalls and the opening is defined the bottom. The LED modules are respectively mounted on the sidewalls of the chambers on the seat and standing on the seat at an inclined angle to allow lights pass through the openings of the chambers. Therefore, each chamber has two light sources from two opposite sidewalls and the lights of the two lights source pass through the opening of the chamber. The LED illuminator provides a wide illuminating angle.

In response to the user selections, the user data entry is routed to both the first application and the second application. Additionally, a list of user data entries can be maintained and displayed, allowing the user to select user data entries from the list and also select an application to which a selected user data entry is to be routed.

Abstract: In a mobile communications device, a conversation identifier is generated for each of a plurality of messages. Each conversation identifier is generated based on addresses of message participants identified in the message. A request to display a particular message of the multiple messages is received. In response to the request, one or more other messages of the plurality of messages having a same conversation identifier as the particular message are identified based on the generated conversation identifiers. At least two of the one or more other messages are displayed concurrently.
