Abstract: A support device having an elongated support member for providing protection to an underside of a vehicle. The vehicle can have one or more pinch welds, such as a vehicle with a unibody chassis.

Abstract: The techniques disclosed herein provide dynamic permissions for controlling messages directed to a presenter of a communication system. For example, during a presentation of an online meeting, a system may selectively permit private messages to be sent to a presenter from designated participants. The private messages sent from the designated participants are displayed to the presenter in a manner that does not allow the other participants to see the messages. For instance, if the presenter is sharing a screen from a computer, the system can determine a set of permitted users allowed to send messages to the presenter. The system configures permissions to cause the messages to be displayed in a manner that allows the presenter to view the messages along with their presentation content, while restricting or suppressing the display of the messages to other non-permitted users. The system restricts the non-permitted users from sending messages to the presenter.

Based on at least one qualification criterion, the system may be configured to identify a sales lead of the sales lead data structure as a sales opportunity. The service ticket translation module may be configured to select data of the sales opportunity for inclusion in a service ticket. By maintaining the selected data of the sales opportunity, the service ticket translation module may be configured to translate the selected data of the sales opportunity into the service ticket. The service ticket translation module may be configured to provide the service ticket to a service board.

Abstract: Systems and methods for predicting feature values in a matrix are disclosed. In example embodiments, a server accesses a matrix, the matrix having multiple dimensions, one dimension of the matrix representing features, and one dimension of the matrix representing entities. The server separates the matrix into multiple submatrices along a first dimension, each submatrix including all cells in the matrix for a set of values in the first dimension. The server provides the multiple submatrices to multiple machines. The server computes, using each machine, a correlation between values in at least one second dimension of the matrix and a value for a preselected feature in the matrix, the correlation being used to predict the value for the preselected feature based on other values along the at least one second dimension. The server provides an output representing the computed correlation.

The bearing cooling system enables heat generated by the bearings to be transferred through the flywheel shaft to a heat sink disposed within a cavity in the end of the flywheel shaft, or to a liquid coolant circulating within the cavity.

Abstract: Methods and systems for energy storage and management are provided. In various embodiments, heat pumps, heat engines and pumped heat energy storage systems and methods of operating the same are provided. In some embodiments, methods include controlling thermal properties of a working fluid by virtue of the timing of the operation of cylinder valves. Methods and systems for controlling mass flow rates and charging and discharging power independent of working fluid temperature and system state-of-charge are also provided.

Abstract: In response to failure of a data storage drive, data previously stored on the failed drive is rebuilt on a replacement data storage drive by executing drive rebuild jobs on a first set of processor cores. While the data previously stored on the failed data storage drive is being rebuilt, a second set of processor cores is used to process host I/O (Input/Output) requests. The host I/O requests processed by the second set of processor cores may be a first set of host I/O requests processed during the data rebuild. When a current total number of outstanding host I/O requests exceeds a threshold maximum number of outstanding host I/O requests, at least one processor core in the first set of processor cores may be used to process a second set of host I/O requests while the data previously stored on the failed data storage drive is being rebuilt.

Abstract: A portable apparatus for configuring a wheel associated with a track is provided. The apparatus is in a fixed position with respect to a rail associated with the track when in operation. The apparatus includes a tool configured to engage the wheel, a position system for positioning the cutting tool in at least two axis, and a computer control. The computer control is coupled to control the positioning system. The positioning system is controlled so that the wheel is configured in accordance with a profile.

Abstract: Provided are methods and systems for, in one aspect, managing content delivered to one or more devices. Methods may comprise receiving a first identifier associated with a user of content. The content may comprise one or more advertisement or placement opportunities. A second identifier may be determined based at least on the first identifier.

Abstract: A method for receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal transmitted by a user device in a wireless network comprises determining which subcarrier frequencies are allocated to the user device; converting the OFDM signal to a frequency-domain values corresponding to the subcarrier frequencies; and decoding the frequency-domain values to recover data symbols encoded by the user device on the subcarrier frequencies. The decoding employs codes that are inverse to, complex-conjugate of, or complementary to a set of complex-valued codes employed by the user device to shape the OFDM signal into a superposition of cyclic-shifted pulse waveforms, wherein each of the pulse waveforms has one of the data symbols modulated thereon.
