A data communication system for unmanned aerial vehicles includes communication links comprising a low-throughput capacity communication link and a high-throughput capacity communication link. The data communication system can also include a base station, to which the unmanned aerial vehicles send aerial data, and from which the unmanned aerial vehicles receive command signals. As the unmanned aerial vehicles perform missions in an open, distant airspace, the unmanned aerial vehicles can gather large volume data such as aerial images or videos. The data communication system allows opportunistic transfer of the gathered aerial data from the unmanned aerial vehicles to the base station when a high-throughput communication link is established. The data communication system allows constant communication between the base station and the unmanned aerial vehicles to send and receive low volume, operation-critical data, such as commands or on-going flight path changes, using a low-throughput communication link.

A parking brake assembly which includes a brake lever, a rotary clutch and a lock-release mechanism which cooperate to selectively lock and release a parking brake. The clutch allows actuation of the brake lever in one direction and prevents movement of the brake lever in an opposite direction. The lock-release mechanism allows selective movement of the rotary clutch and the brake lever together in the opposite direction. A gear mechanism is operatively coupled between the brake lever and the rotary clutch.

Systems and device configurations are provided for reducing misstep, such as miscommunication between a vehicle and a driver that results in applying the incorrect pedal. Vehicle pedal configurations having a positioning element are described. Embodiments include pedal configurations having a pedal pad and at least one positioning element to adjust the pedal pad in response to pedal misstep. Pedal adjustment can include rotation of a pedal pad, rotation of portions of a pedal pad, and multibody pedal pad configurations. According to embodiment, a pedal pad includes vibrational elements to control vibration of the pedal. Embodiments are also directed to a pedal configuration including a flip plate. Systems are provided including a controller to control a pedal configuration and positioning elements. The controller may control the pedal based on a driving mode, such as an assistive driving state wherein operator is instructed to apply a pedal.

A mechanism to prevent an adjustment knob associated with a piece of equipment (e.g. musical instrument or amplifier) from being moved accidentally includes an inner hub held in place on an adjustable shaft. An knob body fits concentrically over the inner hub, and is biased into position over the hub. The bottom of the knob body has locking structure which lockingly but releasingly cooperates with locking structure associated with the piece of equipment to which the shaft is affixed. A biasing structure such as a spring retains the knob body in a first, locked, position, in which the knob body is prevented from rotating, which in turn prevents rotation of the adjustable shaft. However, when the knob body is pulled away from the locking structure against the spring force, the knob body can be rotated, which in turn rotates the hub and shaft shaft. Releasing the knob body allows the biasing structure to urge the knob body back into engagement with the locking structure.

A knob assembly for a gas valve of a cooking appliance and a method of assembling said knob assembly is provided. The knob assembly can include a knob configured to engage a valve stem of the gas valve and a lock assembly including a locking element and a locking plate. The locking element can include at least one cam element that can be engaged by at least one projection carried by the locking plate. The locking plate can be configured to rotate relative to the locking element between a first position in which the at least one projection engages the at least one cam element and a second position in which the at least one projection is disengaged from the at least one cam element, and wherein in the first position the at least one cam element inhibits actuation of the gas valve by the knob.

A control device for an implement system of a machine is provided. The control device is mounted on a support. The control device includes a first gimbal rotatably coupled to the support. The control device also includes a second gimbal rotatably coupled to the first gimbal. The control device further includes a linear actuator having a first end and a second end. The linear actuator is fixed to the second gimbal from the first end. The control device further includes a handle attached to the linear actuator at the second end. The handle is configured to move in conjunction with rotational movements of the first gimbal and the second gimbal, and a linear movement of the linear actuator to control a movement of the implement system.

A detent device for a transmission, having a shifting element, first and second end-position retaining configurations arranged at first and second positions, respectively on the shifting element, the second position is different from the first, and a neutral retaining configuration arranged on the shifting element at a third position different from the first and second positions. A latching first detent element which, depending on the position of the shifting element, latches either at the first or second end positions in the first or second end-position retaining configurations, respectively, and another latching detent element, which latches in the neutral retaining configuration when the shifting element is in its neutral position. The neutral retaining configuration has a retaining contour which is designed and/or orientated differently on the shifting element from the first end-position retaining configuration and from the second end-position retaining configuration. A transmission with a detent device.
