International Classification:
H04B 1/38
US Classification:
455574
Abstract:
The present invention provides an apparatus providing plural wireless transceivers within a desired power budget and associated methods. A plurality of wireless communication modules, each having a lower-power state and a higher-power state are provided, drawing power from a common source. Arbitration is performed to control which of the plurality of wireless communication modules are in the higher-power state, thereby controlling total power delivered by the power source to the plurality of wireless communication modules.

International Classification:
H04L 12/10
H02H 9/02
H02H 9/02
Abstract:
In an embodiment, an apparatus includes a source device including a first current limiter and a second current limiter in parallel with each other and a first transformer and a second transformer; a load device includes a third transformer and a fourth transformer in parallel with each other; and an Ethernet cable is electrically coupled between the source device and the load device, the Ethernet cable including first twisted pair lines and second twisted pair lines. A direct current (DC) voltage is provided to the first current limiter and the second current limiter, the first transformer is electrically coupled to an output of the first current limiter, and the second transformer is electrically coupled to an output of the second current limiter. The DC voltage is transmitted to the third transformer and the fourth transformer in parallel with each other via the first twisted pair lines and the second twisted pair lines. The first twisted pair lines and second twisted pair lines are included in an Ethernet cable electrically coupled between the source device and the load device.

Abstract:
An antenna system includes a first metal housing portion having a metal housing connecting edge, the first metal housing portion having a triangular side profile, and a second non-metal housing portion having a non-metal housing connecting edge, the non-metal housing connecting edge being complimentary to the metal housing connecting edge of the first metal housing, the second non-metal housing portion having a triangular side profile. A first and second dipole antenna are printed on a circuit board positioned in the non-metal housing portion. The first and second dipole antennas are configured such that the direction of the first and second dipole currents are approximately normal to a plane defined by the metal housing connecting edge.
Hollow Core Electromagnetic Coil

International Classification:
H01F 27/28
G06F 3/0346
G06F 3/01
G06F 3/0346
G06F 3/01
Abstract:
An augmented reality/virtual reality (AR/VR) system employs a tracking system for tracking one or more components of the AR/VR system using a generated electromagnetic (EM) field. The tracking system employs an EM coil for generating the EM field or, alternatively, sensing the EM field. The EM coil includes a core substrate and thin metal foil wrapped around the core substrate in three orthogonal axes. The EM coil is effectively “hollow” in that it weighs less than a conventional solid ferrite or ferrous core of comparable dimensions, either through the use of one or more openings formed in the core substrate, the use of a material less dense than ferrite or ferrous materials, the formation of the core substrate as a hollow framework, or a combination thereof. The resulting EM coil thus weighs less than conventional solid-core EM coils, thereby reducing user fatigue and the possibility of misalignment of the EM coil as a result from a drop impact of the device implementing the EM coil.

G06F 3/01
G06F 3/044
G06F 3/01
Abstract:
A method that includes employing several sensors associated with a handheld controller, where each of the sensors is made of one of a hover, touch, and force/pressure sensor, and generating, by one or more of the sensors, sensor data associated with the position of a user's hand and finger in relation to the handheld controller. The method continues with combining the sensor data from several sensors to form aggregate sensor data, sending the aggregate sensor data to a processor, and generating an estimated position of the user's hand and fingers based on the aggregate sensor data.

Abstract:
Systems for ensuring an audible alarm circuit sounds at a minimum magnitude of loudness are provided. Different circuitry embodiments discussed herein are each capable of assisting the audible alarm circuit in maintaining a minimum loudness threshold. Audible alarm circuit operation optimization can be achieved using embodiments that fall within anyone of four general categories: compensation networks, direct drive, dynamic tuning, and microphone feedback based dynamic tuning. Use of such circuitry can increase production yields by compensating for manufacturing variations of alarm components and aging characteristics of the components.
