Abstract: Methods and apparatuses for drying, especially cannabis, are provided. One of the provided methods includes: heating the cannabis in a cavity of a variable frequency microwave oven using at least two different frequencies; measuring temperature of at least 1 cm square of the cannabis at different times during the heating; and controlling the heating based on the temperature measured so that the cannabis is kept for at least 20 minutes at temperatures above 30° C. and below 100° C.

Abstract: A system for aiding the crawling mobility of children or young adults is disclosed. The system consists of central hub supported by four legs. The patient is enclosed in a harness which is coupled to a support cord extending through the central hub. A lifting force partially offsetting the patient's weight is supplied by tension on the support cord, which is locked relative to the central hub via a locking device. Coupling between the support cord and harness is provided by carabineers which are clipped to “D” rings on the harness. The balance point can be adjusted by moving the attachment point to various “D” ring locations.

Abstract: Embodiments of the invention provide methods, devices and systems of transferring information upstream from two or more sets of user devices in a cable communication network. The system, according to some demonstrative embodiments of the invention, may include two or more optical transmitters to transmit two or more respective light beams having two or more respective wavelength spectra, the light beams carrying two or more respective optical signals of upstream information from the two or more sets of user devices, respectively; a combiner to combine the two or more light beams into a multicolor light beam carrying the two or more optical signals; and a multicolor receiver to convert the multicolor light beam into an electrical radio frequency signal carrying the information from the user devices. Other embodiments are described and claimed.
