A handheld surgical device includes a multi-position throttle, rotatably attached to the body of the device, to allow for ambidextrous positioning of a motor speed control lever. The motor speed control lever may interact with a speed control sensor in the body of the device capable of detecting the actuation level of the motor speed control lever in any one of two or more positions.

An apparatus, system, and method are disclosed for managing power consumption in a data storage device. An audit module monitors a power consumption rate of the data storage device relative to a power consumption target. A throttle module adjusts execution of one or more operations on the data storage device in response to the power consumption rate of the data storage device failing to satisfy the power consumption target. A verification module verifies whether the power consumption rate of the data storage device satisfies the power consumption target in response to adjusting the execution of the one or more operations.

Method and system for remote control of a drone helicopter and RC plane using a handheld device is disclosed. Piloting commands and actions are performed using the handheld device, which includes a motion sensor module, with gyro-sensor and g-sensor for controlling roll, yaw and pitch of flying object under relative or absolute coordinate system. The gyro-sensor controls both heading and rotation of flying object in place around its yaw by rotating handheld device around its yaw axis; g-sensor controls pitch and roll by rotating handheld device around its pitch axis and roll axes. Upon determining free falling of flying object, throttle is thereby adjusted so as to land it safely. Flying object further has a camera, and video images are transferred wireless to be displayed on touch screen, and image zoom-in and zoom-out are provided via multi-touch of touch screen. RF and IR capability is included for wireless communication.

A system and method for throttling data access rates through data containers prevents starvation of storage system resources by active clients. A SCSI throttle module of a storage operating system of storage system determines if the number of outstanding access requests associated with the client or initiator group exceeds a preset throttle value.

System and method for processing a safety signal in an autonomous vehicle. Safety signals are typically generated in response to the detection of unsafe conditions or are sent by the vehicle operator. In either case, the safety signals are conveyed using redundant communication paths. The paths include a computer network and a current loop. The safety signals are processed, thereby causing actuators (e.g., linkages) to manipulate input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, accelerator, or transmission shifter). The manipulation ensures the vehicle responds appropriately to the safety signals, for example, by shutting down the vehicle.

Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented.

Methods and apparatus are disclosed for operation of a multiple fuel engine, which runs on a combination of two or more fuels. An electronic control unit (ECU) may be connected to the existing components of an engine system in order to control operation of the multiple fuel engine. The engine system may be mechanically governed or electronically controlled. The ECU inputs operating characteristics of the engine system, determines governing characteristics for multiple fuel operation based on the operating characteristics, and controls the amounts of fuel delivered to the engine based on the governing characteristics. In a preferred embodiment, a dual fuel engine operates using diesel as a first fuel and natural gas as a second fuel. The operating characteristics may include engine speed, throttle position, engine exhaust temperature, gas pressure of the second fuel, gas temperature of the second fuel, boost pressure of an intake manifold, or engine coolant temperature.

The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read/write accesses (I/Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I/O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I/O streams is used to apply controls to guarantee quality of service to all I/O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I/O stream is created that will always be applied to that I/O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I/O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.

A method of operating a transmission of a vehicle. The method includes determining an open loop ratio percentage from an engine RPM input signal and a brake input signal using a first algorithm. Determining a closed loop ratio percentage from the engine RPM input signal, a vehicle RPM input signal and a throttle input signal using a second algorithm. Summing the open loop percentage and closed loop ratio percentage to calculate a ratio command percentage that is used to sum with a swashplate input to actuate a swashplate positioner and operate the transmission.

A method of filtering a plurality of DNS queries, wherein each DNS query includes a query name and a resource record type, includes defining a filter rule including a domain name, a filter type, and a throttle percentage and forming a filter file including the filter rule. The method also includes transmitting the filter file from a server to a plurality of filter proxies, transmitting the filter file from each of the plurality of filter proxies to one or more processing engines, and receiving the plurality of DNS queries at one of the one or more processing engines. The method includes determining a match between the domain name and the query name and between the resource record type and the filter type for a subset of the plurality of DNS queries, and blocking a predetermined percentage (equal to the throttle percentage) of the subset of the plurality of DNS queries.

A flow arrangement (10, 12) for use in a well through one or more underground reservoirs, and where the arrangement (10, 12) is designed to throttle radially inflowing reservoir fluids produced through an inflow portion of the production tubing in the well, the production tubing in and along this inflow portion being provided with one or more arrangements (10, 12).

Requested brake torque and requested throttle torque are assigned opposite algebraic signs in both rollback and non-rollback states. In the non-rollback state, requested motor torque development includes a process step (206) in which requested brake torque and requested throttle torque are algebraically summed. In the rollback state, requested motor torque development includes a process step (218) in which requested throttle torque is substituted for the regeneration torque limit. In the rollback state, the difference between the requested throttle torque and the requested brake torque is compared with a zero vehicle speed regeneration torque limit (228) when the result of comparing the difference between requested throttle torque and the requested brake torque with the regeneration torque limit (222) discloses that the latter difference does not exceed the regeneration torque limit. The result is used to determine respective amounts of motor torque and friction brake torque (230, 232, 234, 236).
