A system for quantification of exercise and physical therapy includes an anchoring module and an electronics module. The anchoring module is removably attached to an object (e.g., a flexible resistive band) or equipped with a clamping mechanism for removably securing the object. The anchoring module also includes an anchoring-module coupling fixture. At least one of the modules includes a sensor (e.g., a force sensor) configured to generate a signal representative of a user's performance during exercise or physical therapy; a processor configured to receive signals from the force sensor; a computer storage medium storing software code and in communication with the processor, wherein the software code includes instruction for processing the signals from the force sensor to quantify the performance; and at least one electronics-module coupling fixture configured to secure the electronics module to the anchoring module coupling fixture.

System and method for quantification of exercise and physical therapy

A haptic actuator includes mechanical links defining a first J-trajectory and mechanical links defining a second J-trajectory as well as a motor coupled to the mechanical links so as to synchronously accelerate a first mass over the first J-trajectory and a second mass over the second J-trajectory. During a first time interval, reactive forces of the first mass accelerating substantially balance reactive forces of the second mass accelerating and during a second time interval reactive forces of the first mass accelerating do not substantially balance reactive forces of the second mass accelerating. This un-balanced condition results in a tap signal being produced.

Complex mass trajectories for improved haptic effect

A multi-layer, super-planar laminate structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations. A layer with electrical wiring can be included in the structure for delivering electric current to devices on or in the laminate structure.

A method for manufacturing a millimeter scale electromechanical device includes coupling a stainless steel ply to a polymer carrier ply, coating the stainless steel ply in a photo resist material, masking the photoresist material, exposing the photoresist material to cure a portion of the photoresist material, developing the photoresist material to remove uncured photoresist material from the stainless steel ply, chemically etching the stainless steel ply to remove a patterned portion of the stainless steel ply, dissolving the polymer carrier ply to release unwanted chips of the stainless steel ply, and adhering the patterned stainless steel ply to a flexible material ply to form a sub-laminate.

High-volume millimeter scale manufacturing

A system and methods for aerosol delivery of an entity or agent are disclosed. The system and methods can include a target application surface. A nebulizer can be located in close proximity to the target application surface. The nebulizer can include a chamber to hold the entity, a nozzle plate including one nozzle, and a piezoelectric element coupled to the nozzle plate. A power source can be coupled to the piezoelectric element. The power source, when activated, can energize the piezoelectric element to vibrate the nozzle plate to cause the entity to be nebulized through the nozzle to impact the target application surface.

Devices and methods for in vitro aerosol delivery

A circuit for driving a plurality of capacitive actuators, the circuit having a low-voltage side, a high voltage side and a flyback transformer between the two. The low-voltage side comprises first and second pairs of low-side switches connected in series across an input voltage. The flyback transformer has a primary winding connected to the two pairs of switches. The high-voltage side has a pair of switches connected between the secondary winding of the flyback transformer and a ground and a plurality of capacitive loads and bidirectional switches to connect the loads to the secondary winding of the flyback transformer and a ground.
