Abstract: An electrical energy storage device (20) includes a substrate (22), an anode layer (30), a cathode layer (26), and a separator layer (28) between the anode layer and the cathode layer. The substrate has multiple sets of intersecting cavities (21) passing through the substrate in different directions. The anode layer, cathode layer, and separator layer are formed over a surface of the substrate within the cavities.

Abstract: An agricultural robot for monitoring a growing site, the robot comprising: an autonomous mobile platform; an acoustic sensor module mounted on the autonomous mobile platform and comprising: a speaker operable to transmit a directional acoustic signal at an object; and a microphone operable to register a reflection of the acoustic signal from at least one plant in the growing site; and a sound analyzer operable to time-index the registered reflection, and map a location in the growing site of the at least one plant responsive to the registered reflection.

Abstract: An agricultural robot for monitoring plants in a growing site, the robot comprising: a sensor module comprising: a speaker operable to transmit a directional acoustic signal at an object; and a microphone operable to register a reflection of the acoustic signal; a sound analyzer operable to time-index the reflection received by the microphone and maps a location of the object that reflected the received acoustic signal; and an autonomous mobile platform onto which the sensor module is mounted.

Abstract: A micropump for pumping a fluid, the pump comprising: a tube formed from a piezoelectric material and having inner and outer surfaces; a plurality of electrodes electrifiable to generate vibrations in the tube; and at least one voltage source that applies voltages to the electrodes to generate a displacement traveling wave that propagates along the tube and causes fluid in the tube to flow through the tube.

Abstract: A force sensor device has at least three arcs distributed around a central axis. The arcs have integrated sensing elements that measure strain applied on the arc resulting from a force applied on the central axis.

Abstract: A capsule includes a main body with at least one tail connected to the main body. At least two coils are disposed on each tail such that the coils are responsive to a magnetic field interacting with the coils such that a force is exerted on the tail. The capsule is controlled through application of a varying magnetic field with a constant current in the coils and/or by providing varying a current in the coils that interact with a constant magnetic field. The capsule can be disposed in a cavity, and the magnetic field can be provided from outside the cavity to affect movement of the capsule. An MRI device can be configured to control and image the capsule.
