摘要:
A man-machine interface which provides tactile feedback to various sensing body parts is disclosed. The device employs one or more vibrotactile units, where each unit comprises a mass and a mass-moving actuator. As the mass is accelerated by the mass-moving actuator, the entire vibrotactile unit vibrates. Thus, the vibrotactile unit transmits a vibratory stimulus to the sensing body part to which it is affixed. The vibrotactile unit may be used in conjunction with a spatial placement sensing device which measures the spatial placement of a measured body part. A computing device uses the spatial placement of the measured body part to determine the desired vibratory stimulus to be provided by the vibrotactile unit. In this manner, the computing device may control the level of vibratory feedback perceived by the corresponding sensing body part in response to the motion of the measured body part. The sensing body part and the measured body part may be separate or the same body part.

A tracking device includes a motor, top and bottom propellers of opposite sense attached to the stator and rotor of the motor for rotation in opposite directions. Target sensors are provided on the propellers and signals from the target sensors are supplied to a controller that controls the rotation of the motor and the propellers. The tracking device also includes a power supply for the motor and the controller.

A touchable user interface including multiple robotic modules that can “walk” over each other to allow reconfiguration of the interface. Each module preferably includes motive devices as well as connective devices communication between the modules and a control unit that send commands to the interface, thereby enabling its reconfiguration. Depending on the needs of the user/builder, the interface can be an input interface, or both. The interface can also act as robotic appendage/manipulator capable of engaging and manipulating a wide variety of objects and/or substances by engulfing such objects and/or substances in “pseudopods” and structural voids which the modules are moved by instructions from the control unit.
摘要:
A movable robotic module including a framework defining a set of vertex elements, a set of edge elements, or a set of face elements, with the framework substantially shaped to permit face centered cubic packing. Each module includes a pivot mechanism on its framework to permit rotation of the framework with respect to other movable robotic modules. A power unit supplies operational power to each module, the power being used for rotation of the module, sensor and/or a control unit connected to the pivot mechanism and/or the power unit to control rotation of the framework.

A valve for redirecting fluid flow has a valve chamber supporting fluid flow, with the valve chamber having an inlet, a first outlet, and a second outlet. The valve chamber can be closed or partially open. The flap element is movable to alternatively block the first outlet and the second outlet. In or immediately adjacent to the valve chamber are opposing first and a second catch mechanisms for controllably latching the flap element to block respectively the first outlet and the second outlet. The first and second catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap element. Once the first or second catch mechanism is disabled, the flap element is free to move to another position, provided it can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap element, an impulse mechanism kicks the flap element into the valve chamber, away from one of the first and second catch mechanisms, after one of the first and second catch mechanisms is controllably brought into the disabled state. Since the flap element is unstable, oscillations of the flap element in the fluid flow will eventually bring the flap element into catchment range of one of the first and second catch mechanisms in an activated state.

A system for detecting and damping vibrations in printer components, mechanical devices, buildings, or large structures has a plurality of light beam detectors for generating signals corresponding to a reference light beam position. The light beam detectors are partially transparent to allow passage of the light beam through the detector, permitting multiple detectors to use the same reference light beam. The detectors are attached to vibration susceptible structural elements, with detected movement of the light beam with respect to the partially transparent light beam detector corresponding to movement of the vibration susceptible structural element. Motion control units connected to the detectors can be used to control or damp detected vibrations in real-time.

A robotic device may include a plurality of concatenated assemblies, a tendon slidably connected to the plurality of concatenated assemblies, and an actuator that moves the tendon. Each assembly of the concatenated plurality may include a joining member that neighbors an adjacent assembly, a linkage that may fixedly connect to the joining member and may pivotably connect to the adjacent assembly, and an appendage that may extend from the joining member to a length. The appendage may include a connector through which the tendon may be connected to slide through. The connector may be adjustably disposable along the length of the appendage to a specified position thereon. The appendage may extend in a direction at a specified angle relative to the linkage.

A transport apparatus for transporting materials or objects on substantially vertical structures for installation, deployment, inspection and repair purposes includes gripping mechanisms having a conformable gripping portion. The gripping mechanisms are separated by links, which are mutually attached to each other to permit angular rotation of the links relative to each other about a pivot point. A latching mechanism provides the capability for the gripping portion to be opened as well as secured for operation.

The Pendulum Whiteboard Printer is a fully-automatic robotic device for marking or otherwise effecting whiteboards, pinboards, or other vertical surfaces. The physical device consists of an effector platform suspended by two suspension wires whose lengths are adjusted by motorized spindles mounted above and on either side of the board surface. The position of the effector platform is adjusted by winding and unwinding the wires. Electrical power is supplied to the effector platform through the suspension wires or through an on-board battery. Control of a pen and/or other apparatus on the effector platform is achieved through modulation of the power voltage. A parking facility is provided as a resting place for the effector platform for such purposes as keeping pens from drying out.

A modular electronic assembly comprising a plurality of modules. Each modules power connection plates including a single dynamically defined root power connection plate and at least one dynamically defined branch power connection plate. Each module has a power distribution controller for dynamically defining the single root power connection plate and branch power connection plate(s) and distributing power between the modules only from branch power connection plates to root power connection plates of the modules connected by power connection plates. A constant current power supply is connected to at least one of the plurality of modules to provide a substantially constant current to all of the plurality of modules connected together by power connection plates.
