Abstract: Devices and methods for bio-specimen refrigeration are provided. In an embodiment, the bio-specimen refrigeration devices of the present disclosure include a housing having a lid and a base portion, wherein the lid is selectively moveable between an open position and a closed position; a coolant cartridge chamber disposed in the housing and configured to fluidically couple with a coolant cartridge disposed in the coolant cartridge chamber; and a cooling chamber disposed in the housing and configured to receive a fluid coolant from the coolant cartridge, wherein in the closed position, the lid seals the cooling chamber.

Abstract: An electronic candle produces light using light emitting diodes (LEDs) or other electronic sources of light, rather than a flame, and is intended to operate the LEDs in a fashion that simulates a burning candle. The electronic candle includes a base and LEDs within a bulb and surrounded by a dome to provide a diffusing effect for light generated within the electronic candle. A memory accessible by a processor contains stored programming instructions causing the LEDs to illuminate under control of the processor, in accordance with particular modes of operation, varying from one mode to another after brief periods of time and in a random way. Each mode defines an apparent flame position having a radial position, angular position, and intensity of the simulated flame.
