Devices and methods for vaporizing active ingredients of a selected substance for inhalation using a portable vaporization device are provided herein. In certain aspects, the device includes a portable power source, a heating portion, an inhalation sensor, a temperature sensor, a distal light source, and a grinding portion. In response to an inhalation by a user, the power source energizes a heating element of the heating portion so as to heat air flow to a desired vaporization temperature within a few seconds of detecting inhalation, using convection and radiative heating. The device may include a receptacle for receiving a cartridge containing a pre-prepared substance, such as a liquid, gel, powder, or solid brick, and a grinding portion to allow a user to grind intact portions of cellulose-based material into smaller pieces to facilitate vaporization by manually rotating portions of the device relative to each other.

Operational modes for a cooking appliance employing combination cooking technology

A cooking appliance includes a controller for establishing a plurality of operating modes for heating an oven cavity. Specifically, the controller establishes one of a pre-heat mode, a ready mode, a first low power mode and a second low power mode for controlling a temperature of the oven cavity. Upon selecting a temperature for the oven cavity, the controller operates a radiant heating device, a convection fan and a convection heating device at full power to establish the selected temperature. After the selected temperature is achieved, the controller switches to a ready mode and reduces heat output of both the radiant heating device and the convection heating device, while also reducing fan speed. After respective periods of time in which a door of the appliance is not opened, the controller switches to first and second low power modes to conserve energy.

Method and apparatus for manufacturing filters

A problem in the manufacture of filters using tubular membrane bundles is keeping potting material from flowing into the openings at the ends of the tubes. A preferred embodiment of a method for manufacturing a tubular membrane filter employs a non-contact heat source such as radiant heating to melt the tips of the tubular membranes. This prevents the migration of potting material into the tubes when the potting material is flowed into the ends of tube bundles during the manufacturing process for a filter.

Stable cold field emission electron source

A cold field emission (CFE) electron source for a focused electron beam system such as a transmission electron microscope (TEM), scanning transmission electron microscope (STEM), or scanning electron microscope (SEM) is disclosed. The source employs an emitter enclosure electrode behind the CFE tip which, in conjunction with the extractor electrode, defines a closed volume that can be thoroughly cleaned by electron impact desorption (EID) and radiative heating from a heated filament located between the emitter enclosure electrode and extractor electrode. The extractor electrode may have a counterbore which restricts backscattered electrons generated at the extractor from reaching portions of the source and gun which have not been cleaned by EID. Pre-cleaning of the emitter enclosure electrode and extractor electrode prior to cold field emission substantially improves both source emission stability and frequency noise characteristics, enabling source operation over time intervals adequate for application to TEMs, STEMs, and SEMs.
