Abstract: Disclosed herein, among other things, are systems and methods for temperature detection for hearing device applications. A method includes obtaining a first temperature measurement from a first sensor from a first side of a housing of a hearing device, and obtaining a second temperature measurement from a second sensor from a second side of the housing. The first temperature measurement is compared to the second temperature measurement, and a determination is made whether the hearing device is positioned on a right side or a left side of a wearer of the hearing device, based on the comparison. The hearing device is configured as a right device or a left device based on the determination.

Abstract: An ear-wearable device includes a receiver that produces sound into an ear canal and an inward-facing microphone determining sound pressure resulting from: the sound reproduced by the receiver into the ear canal; and acoustical noise leaking into the ear canal. A structural vibration sensor is coupled to detect at least one of body-induced vibrations and receiver-induced vibrations and produce a sensed vibration signal in response. A sound processor of the ear-wearable device is operable to determine an error signal from the inward-facing microphone and determine an active noise cancellation (ANC) signal based on the error signal. The vibration signal is used to reduce the impacts of vibrations on ANC processing within the ear-wearable device.

The second charging interface comprises a second anode contact having a contact surface and a displaceable second cathode contact. An arrangement is configured to displace at least a portion of the second cathode contact above the contact surface to facilitate electrical contact between the first and second cathode contacts prior to electrical contact between the first and second anode contacts.

Abstract: The present invention describes a method which outlines a process for conversion of CBD to a ?9-tetrahydrocannabinol (?9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the ?9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% ?9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce ?9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% ?9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the ?9-THC using distillation and collecting an essentially pure fraction of ?9-THC using additional distillation or enrichment form of purification.

Abstract: A tool to facilitate attachment and detachment of cable connectors. The tool includes a backstop plate for engaging a cable connector receptacle housing, an overmold plate for engaging a cable connector being insertibly connected into a cable connector receptacle, and a rotational means passing through a rotational acceptor formed as part of the overmold plate and rotatably attached to the backstop plate. The rotational means causes the overmold plate to approach the backstop plate upon application of a first spin direction of the rotational means and causing the overmold plate to recede from the backstop plate upon application of a second spin direction of the rotational means. The overmold plate approaching the backstop plate causes the engaged cable connector to be insertibly connected into the cable connector receptacle housing and the overmold plate receding from the backstop plate causes the engaged cable connector to be removed.
