An apparatus for mounting on a circuit board is provided. The apparatus may include a circuit board mount packaging and a battery. The circuit board mount packaging may include a cavity, a first internal lead, and a second internal lead. The first internal lead may be connect to a first external pin and the second internal lead may be connected to a second external pin. The battery may be disposed within the cavity of the circuit board mount packaging. The battery may comprise an anode and a cathode. The anode may be wire bond connected to the first internal lead and the cathode may be wire bond connected to the second internal lead.

Chip packaged battery

A capacitive liquid crystal (LC) biosensor for sensing a target biological agent includes a support board; a flow channel on the support board, the flow channel having an inlet port at a first end and an exit port at a second end; at least two electrodes, the at least two electrodes including a first electrode on a flow channel first surface and a second electrode on a flow channel second surface opposite the flow channel first surface; an electricity source connected to the first electrode and the second electrode; and an LC sensor array positioned within the flow channel. An LC sensor array includes a sensor support surface; wells positioned on the sensor support surface; an organic LC phase within each of the plurality of wells; and an aqueous phase having an analyte positioned above the organic LC phase within the wells.

Capacitive liquid crystal biosensors

Compliant manipulators are provided, in which the manipulators include a plurality of slideably interlocked filaments each having a proximate end and a distal end. The interlocked filaments can be formed from a flexible material. The compliant manipulators can also include at least one filament-actuating device operatively connected to the respective distal ends of the plurality of slideably interlocked filaments. The at least one filament-actuating device can be manipulated directly or remotely to push and/or pull the respective filaments to impart a desired movement to the manipulator. The stiffness or flexibility of the manipulators can also be controlled to provide varying degrees of stiffness during use.

Adjustable stiffness morphable manipulator

A vehicle includes a head section having a selectively actuated first plurality of claws, a tail section having a selectively actuated second plurality of claws, and a linear actuator operably coupling the head section to the tail section. The linear actuator is configured to be selectively extended and retracted. The vehicle is configured to move forward within an enclosed space by extending the linear actuator, while the first plurality of claws is not actuated and the second plurality of claws is actuated, then retracting the linear actuator, while the first plurality of claws is actuated and the second plurality of claws is not actuated.

Vehicle for navigating within an enclosed space

A time-temperature indication device includes a first reservoir having a fluid disposed therein, and a capillary tube. The capillary tube is disposed proximate to the first reservoir to receive fluid from the first reservoir responsive to changes in viscosity of the fluid based on changes in temperature. The capillary tube restricts flow of the fluid out of the first reservoir into the capillary tube to enable fluid flow only in a single direction.
