Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual return mechanism. The powered handle can also include a retention mechanism to prevent unintentional movement of drivetrain components upon actuation of the manual return mechanism. For example, the retention mechanism can apply a direction-dependent frictional force on an actuation shaft of the handle assembly to prevent unintentional movement of the actuation shaft towards a distal end of the handle assembly. The retention mechanism can include a featherboard-like configuration with a plurality of ribs oriented transversely to the actuation shaft to restrict movement of the actuation shaft in one direction while allowing movement of the shaft in the opposite direction.

Abstract: A job that receives as input a data stream is executed. For the job, it is iteratively determined a backlog growth over a first period of time; a backlog volume; and whether to adjust a quantity of processing resources. For each iteration for which the quantity of processing resources allocated to the job are determined to be adjusted, adjusting the quantity of processing resources allocated to the job. For each iteration for which the quantity of processing resources allocated to the job are determined not to be adjusted, maintaining the quantity of processing resources allocated to the job.

Abstract: A data parallel pipeline may specify multiple parallel data objects that contain multiple elements and multiple parallel operations that operate on the parallel data objects. Based on the data parallel pipeline, a dataflow graph of deferred parallel data objects and deferred parallel operations corresponding to the data parallel pipeline may be generated and one or more graph transformations may be applied to the dataflow graph to generate a revised dataflow graph that includes one or more of the deferred parallel data objects and deferred, combined parallel data operations. The deferred, combined parallel operations may be executed to produce materialized parallel data objects corresponding to the deferred parallel data objects.

Abstract: Technologies for determining the location of a telematics device during communication mode switching of the telematics device include switching a communication processor of the telematics device between a location mode and a data mode. In the location mode, the communication processor is configured to receive location data from a location beacon system and determine a present location of the telematics device. In the data mode, the communication processor is configured to transmit and receive data communications from a remote computer system(s). While in the data mode, the telematics device may estimate its location based on a last determined present location and inertial sensor data received from inertial sensors of the telematics device using dead reckoning.

Abstract: Technologies for switching between communication modes in a telematics device includes a communication subsystem having a communication processor electrically coupled to a location antenna to receive location data form a location beacon system and a data antenna to communication with a remote computer system(s). The communication processor may have multiple modes of operation including a location mode in which the communication processor is configured to receive and process location data from the location beacon system and a data mode in which the communication processor is configured to transmit and receive data communications from the remote computer system(s). The communication subsystem may control the operating mode of the communication processor by switching the communication processor between the location mode and the data mode according to a determined switching duty cycle.
