Abstract: A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

Abstract: A protective clothing equipment is provided that is comfortable, stabilizing, and compatible with varying types of surfaces. One embodiment of the protective clothing equipment includes a shell, padding disposed in front of the knee of the wearer, the padding including a non-uniform stiffness.

Abstract: An emergency call is initiated on behalf of a remote user by another software user who determines that the remote software user is experiencing an emergency event. During a real-time communication, a remote emergency alert is received from a first client device associated with a first user. The remote emergency alert identifies a second user associated with a second client device while the first client device and the second client device are in communication via real-time communication software. Based on location information determined for the second client device responsive to the remote emergency alert, an emergency call is initiated with a public safety answering point local to the second client device for indicating an emergency event associated with the second user to the public safety answering point on behalf of the second user.

Abstract: A system includes a network and a telephony server. The network is associated with an independent carrier (IC), a native carrier, or both. The network includes a telephone gateway, an internet gateway, a first device associated with the IC, and a second device associated with the native carrier. The first device communicates with the telephone gateway. The second device communicates with the internet gateway. The telephony server is associated with the native carrier. The telephony server supports traffic from the first device and the second device. The telephony server includes a PBX and a session border controller (SBC). The SBC communicates with the telephone gateway via a session initiation protocol (SIP) trunk.

Abstract: A luminometer apparatus has a light-tight box (12) into which a cuvette (2) containing a sample and a reagent are located for producing a phosphorescent reaction. The phosphorescent reaction is detected by a photodetector (PD) and a shutter (3) is interposed between the cuvette and the shutter. Output signals from the photodetector are applied to a circuit arrangement (FIG. 4) which detects the phosphorescent reaction at predetermined intervals and by subtracting the successive values of light from one another so a measured peak value of light intensity is determined. The shutter is closed and the dark current signal of the photodetector is determined and subtracted from the measured peak value. A true peak intensity of the emitted light is thus derived and the concentration of the material being assayed is calculated by raising the peak intensity to the power n where n has a value between 0 and 9 predeterminedly derived for the sample.

Abstract: A single-crystal ingot I of boron-doped silicon is electron-beam heated in ionized hydrogen. Using an electrode E to apply an electric field from the ingot I towards a heated substrate S, which is r.f. biassed, an amorphous boron-doped silicon film deposits on the substrate S.Intrinsic and n-type material can also be produced.

Abstract: In a hot water process for extracting bitumen from tar sands comprising forming a mixture of tar sands and water, settling the mixture in a primary extraction zone to form an upper bitumen froth layer, a middlings layer and a sand tailings layer, passing a part of the middlings layer to an air scavenger zone to recover additional bitumen therefrom, the improvement which comprises adding the aerated bitumen-depleted aerated middlings material from the air scavenger zone to the mixture of tar sands and water before the settling step.

Abstract: In a hot water process for extracting bitumen from tar sands comprising forming a mixture of tar sands and water, settling the mixture in a primary extraction zone to form an upper bitumen froth layer, a middlings layer, and a sand tailings layer, passing a part of the middlings layer to an air scavenger zone to recover additional bitumen therefrom, the improvement which comprises aerating the mixture of tar sands and water before separating bitumen froth from the mixture in a gravity settling zone. This aeration can be accomplished by adding an aerated recycle middlings stream to the tar sands water-mixture prior to the settling step.

Abstract: A method for improving recovery in a hot water process for extracting bitumen from tar sands comprising adding bitumen-depleted middlings recovered from a scavenger zone to the sand layer in a primary extraction vessel at a point below the surface of the sand.
