Abstract: A mechanical eyeball includes an outer housing shaped as an ocular surface configured to rotate about a first rotational axis and a second rotational axis that intersect at a fixed center point. The outer is housing is coupled to a mechanical assembly, and the mechanical assembly is contained within a volume associated with the mechanical eyeball. The mechanical assembly can include a stationary gear train and rotatable components that rotate relative to the gear train. The rotatable components are configured to cause rotation of the outer housing about one or more rotational axes. The volume may be substantially the same volume of a human eye. The mechanical assembly is coupled to one or more drivers configured to actuate rotation of the outer housing.

Abstract: An animatronic device includes a mechanical eyeball configured to rotate about a first rotational axis and a second rotational axis that intersect at a fixed center point. A controller is configured to generate eye movement instructions that cause the animatronic device to rotate the mechanical eyeball about at least one of the first rotational axis and the second rotational axis. The eye movement instructions are generated based on an eye tracking system used to track movement of an eye of a user. The controller maps the tracked eye movement to movement of the mechanical eyeball and generates eye movement instructions based on the mapping.

Abstract: An adjustable holder assembly is disclosed that has a mounting structure and a display support with a center of gravity and being rotatably coupled to the mounting structure for rotation about an axis of rotation. The display support has a support structure and an adjustable counterweight assembly with a counterweight and an adjustment mechanism connected to the counterweight. The counterweight is spaced apart from display support's axis of rotation. The adjustment mechanism is adjustable to move the counterweight in a direction normal to the axis of rotation to move the center of gravity toward or away from the support structure. The adjustable counterweight is configured to provide a force feedback to a user pressing on an input portion of the computer tablet by moving the center of gravity toward or away from the support structure.

Abstract: A modular fiber optic patch panel system is disclosed. The system includes an enclosure and at least one patch panel module mounted in the enclosure. The enclosure includes a chassis with multiple module bays, each configured to receive a corresponding patch panel module. The patch panel modules each include a module housing, an input connector and an output connector. An optical directional coupler is connected to the input connector and a photodiode is positioned adjacent the optical directional coupler to measure an optical power level conveyed on the optical fiber. A data acquisition device is connected to the photodiode to capture the optical power level data and a microcontroller is connected to the data acquisition device to store the data.

Abstract: The disclosure is directed to a sensor in which the sensing capability is made possible without need for having an independent power source of the sensor. The sensor can include a standard RFID tag, a reed switch, and an antenna. The reed switch can be closed (or opened, as appropriate) when exposed to a magnetic field. The magnetic field can be provided in various ways, e.g., an electromagnet, a permanent magnet, or an electromagnetic field (e.g., inductors wrapped around a power cord). When the reed switch is closed or opened (upon exposure to the magnetic field), the RFID tag's antenna can respond (or fail to respond, as appropriate) to a transmission signal it receives from a base station by sending a “heartbeat” signal that enables sensing in a variety of IoT applications. The sensor can be used for detecting an opening or a closing of a window.
