Abstract: A method and apparatus for a certificate authority system providing authentication to a plurality of devices associated with an organization are described. The method may include receiving, at the certificate authority system, a request from a device to sign authentication information of the device, wherein the device is associated with the organization. The method may also include sending a challenge to the device to perform an action with a system other than the certificate authority system, and receiving the response to the challenge from the device. Furthermore, the method may include verifying that the response was generated correctly based on the challenge, and signing the authentication information of the device with one or more keys of the certificate authority system as an authentication of an identity of the device.

Abstract: A system and method for ordnance delivery that includes a projectile that, when embedded into a target, can transmit information such as location and position information to a computing device. The computing device can relay this information to a weapon system that can deliver ordnance to the target accurately.

Abstract: A connection hub includes a housing coupled to a universal serial bus (USB) cable that includes a plug for electronic devices. A housing of the connection hub includes a number (N) of ports and switches. The connection hub includes 1-to-N connections between the USB cable and the N ports, where each of the N ports includes a data line and/or a power line. The switches each include a mechanical component that is movable between a first position that activates a private mode and a second position that deactivates the private mode. A data line of a particular port is disabled when the private mode is activated, and a particular power line of the particular port is enabled when either the private mode is activated and when the private mode is deactivated.

Abstract: Provided is a method for detecting the trajectories of one or more targets in the field of view of one or more sensors, the method comprising: receiving one or more sensor frames corresponding to the one or more sensors; defining a space of allowable target states for the one or more sensor frames; specifying a set of potential target trajectories, each comprising one allowable target state for each of the one or more sensor frames; specifying target signal parameters for each of the allowable target states, such that the target signal parameters predict the expected target signal contribution corresponding to the one or more sensor frames; specifying a data fidelity objective to quantify how well the target signal parameters match the one or more sensor frames; specifying a sequence of one or more sparsity objectives to penalize a number of detected targets; determine the trajectories of one or more targets as follows: obtain values for all the target signal parameters in all the sensor frames, the obtained

Abstract: Provided is an array antenna divided into a plurality of sub-arrays disposed along a first dimension, wherein each sub-array comprises: a plurality of frequency scannable elements disposed along the first dimension and a plurality of phase shifters or transmit/receive (T/R) modules disposed along a second spatial dimension, each phase shifter or T/R module connected to a plurality of frequency scannable elements disposed along the first spatial dimension; and one or more processors being configured to generate a recurring radar waveform having a transmit portion, the transmit portion having multiple successive pulses at different frequencies to generate transmit beams by the array antenna at different angles in the first dimension; control at least one of the plurality of phase shifters or T/R modules along the second dimension to cause the transmit beams to be generated by the array antenna at different angles in the second dimension; and process return signals received by the plurality of sub-arrays to esti

Abstract: A Universal Serial Bus (USB) cable includes a connector and a switch. The connector includes a housing configured for gripping by a user to manually insert/remove the connector to/from a port of an electronic device. The connector includes a power line configured to enable transfer of power to the electronic device and a data line configured to enable exchange of data with the electronic device. The switch is integrated into the outer surface of the housing and includes, for example, a toggle that is mechanically movable between a first position that activates a private mode and a second position that deactivates the private mode. The exchange of data with the electronic device is only enabled while the toggle is in the second position, and the transfer of power to the electronic device is enabled regardless of whether the toggle is in the first position or the second position.

Abstract: The installation of an abrasion resistent polymer liner in the production tubing string of a well which is being produced by rod pumping for the principal purpose of reducing rod wear on the tubing string, and wear on the rods and/or the rod couplings. In a preferred embodiment of the invention, the polymer liner is characterized by an extruded polymer material having a high density, which is abrasive resistant, and which has a coefficient of friction that is much lower than the coefficient of friction of metal tubing, such as high density polyethylene.
