Abstract: The present disclosure 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 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.

The recorded signal is used to determine whether the user has a tremor. Upon determining the user has the tremor, a notification is provided indicative of the presence of the tremor to one or more of the user or a clinician.

Abstract: A system and method for hardening security within a physical location. At least one cable in the physical location is monitored for errors. In response to detecting an error on the cable a cable fault analysis procedure is performed to determine the location of the fault on the cable. A probability that the fault is caused by a threat actor is calculated based upon the location of the fault on the cable. The probability can be calculated using mixture modules of known nonthreat locations using supervised learning approaches. At least one security protocol at the physical location is implemented in response to the location of the fault having a probability that the fault location is related to a threat actor exceeding a threshold value.
