Abstract: Systems and methods are described for managing communications amongst mobile computing units. The invention includes location detection, three-dimensional proximity detection and alert systems for and amongst mobile units, through the utilization of low-power local communications protocols. The systems and methods minimize power consumption by the mobile units, and enable for robust, reconfigurable real-time location and asset tracking.

Abstract: An intelligent tracking system generally includes one or more tracking devices, some of which may be passive tracking devices. Each passive tracking device includes one or more transceivers and is energized by an energizing signal. Some of these passive tracking devices may operate in a first communication mode or a second communication mode based on the energizing signal. Some tracking devices may include encryption modules or authentication modules. Some of these devices may incorporate a bulk acoustic wave oscillator.

Abstract: According to some embodiments of the present disclosure, an intelligent tracking system is disclosed. The intelligent tracking system includes one or more passive tracking devices, an exciter, and a tracker. Each passive tracking device includes one or more transceivers and is energized by an electromagnetic frequency. In response to being energized each passive tracking device transmits a short message. The exciter emits the electromagnetic frequency. The tracker receives short messages from the one or more passive tracking devices and confirms the presence of the one or more passive tracking devices in a vicinity of the tracker based on the received messages.

Abstract: An apparatus includes a frame component of a head-mounted device (HMD), an eyepiece, a battery, a processor, a heat pipe, and a hinge. The frame component includes a first compartment, a second compartment, and a channel connecting the first compartment and the second compartment. The heat pipe may extend from the first compartment to the second compartment through a channel and may be configured to transfer heat from the processor to the battery. A rate of heat transfer through the hinge may be greater than a threshold value when the hinge is in an open conformation that configures the frame component to be positioned along the side of the head. The heat transfer through the hinge may be smaller than the threshold value when the hinge is in a folded conformation that configures the frame component to be positioned for storage.

Abstract: A system for monitoring a beehive includes a sensor bar. The sensor bar has a physical size and shape to function as a frame bar of a honeybee frame that slides into a chamber of a beehive. The sensor bar includes an enclosure having a plurality of holes, a microphone disposed within the enclosure to record sound emanating through the holes from the beehive, and at least one interior environmental sensor disposed within the enclosure to measure an interior environmental characteristic of the beehive.

Abstract: In certain embodiments, chemical sensing may be facilitated. In some embodiments, a fluid sample may be received at a sensing device having one or more chemical sensitivities. A reaction of the sensing device to a chemical in the fluid sample may be detected based on the one or more chemical sensitivities of the sensing device. For example, a sensing unit within the sensing device having a particular chemical sensitivity may react with a chemical in the fluid sample. In some embodiments, the reaction may be a change in resistivity or piezoresistivity. One or more chemicals in the fluid sample associated with the reaction of the sensing device may be identified. In some embodiments, machine learning models or neural networks may facilitate the identification of chemicals associated with the reaction.
