Abstract: An example of a lighting device including a light source, a modulator and a processor. The processor is configured to control the light source to emit light for general illumination and control the modulator to modulate the intensity of the emitted light to superimpose at least two sinusoids. Frequencies of the at least two sinusoids enable a mobile device to infer the physical location of the lighting device.

Abstract: A light source emits a modulated light, and a radio-frequency transceiver disposed therewith emits a radio-frequency signal. A mobile device may receive either or both signals and determine its position based thereon. The light and radio-frequency sources may be disposed in node in a network of said sources, and the nodes may communicate via the radio-frequency transceivers.

Abstract: A medical device is described having a handle and an end effector coupled to the handle. The end effector has at least one electrode for providing electrical signals to a tissue or vessel to be treated. An RF drive circuit is provided for generating an RF drive signal that is applied to the end effector electrode. The RF drive circuit includes a resonant circuit and a frequency controller is used to vary the frequency of a signal passed through the resonant circuit in order to control the power supplied to the end effector electrode.

Abstract: A lighting network includes a plurality of nodes, each having a node identifier. Each node includes a light source and a radio-frequency (RF) transceiver that transmits RF signals to and receives RF signals from other ones of the nodes. Each signal includes a data packet having a packet identifier, a destination node identifier and a payload. Each node compares the packet identifier of a received packet to a list of packets identifiers and when the packet identifier is not in the list, adds the packet identifier to the list. If the node is the destination node for the packet, the node then executes a command contained in the payload of the packet. If the node is not the destination node, the node retransmits the packet to the nodes that are within range of the RF transceiver. When the packet is in the list, the node discards the packet.

Abstract: The present invention provides a flow apparatus (10) having a flow control valve (12) having a housing (14), an aperture (16), an aperture obturator (18) and an actuator (20) for moving said obturator (16) between a first closed position and multiple open positions (B-L), characterised by a valve position monitor (21) for monitoring the position of the valve (12) and comprising a plurality of discrete sensors (28a to 28e) associated with a plurality of open positions (B-L) of said valve for monitoring the presence or absence of one or more members (26) movable with said valve (12). The arrangement may be used to monitor the valve position and such monitoring may be of use in the prediction of the amount of fluid remaining within a cylinder (32) to which it has been attached.

Abstract: The invention relates to a process and system for the production of a solvent using monophasic solventogenic Clostridia in a single stage process. More particularly, the process and system relate to the use of a culture vessel for culturing mono phasic solventogenic Clostridia, wherein cell growth of the Clostridium is monitored and optimised by the addition of controlled Q amounts of culture media and/or the removal of controlled amounts of solvent. The process and system may particularly be used to produce solvents such as butanol, acetone and ethanol.

Abstract: The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by coupling a base of the cartridge to a carriage that is transported via a track. The track transports the carriages between various substations at which one or more parts are added to the base. The carriage may be lifted from the track by a lifter mechanism at each substation in order to perform assembly operations on the base. An inspection system may inspect the cartridges at various stages of completion at or between the various substations.

Abstract: A medical device is described having a handle, a shaft coupled to the handle and an end effector coupled to the shaft. In one embodiment, the device includes an ultrasonic transducer and is arranged so that ultrasonic or electrical energy can be delivered to a vessel or tissue to be treated. Various novel sensing circuits are described to allow a measure of the drive signal to be measured and fed back to a controller. An active fuse circuit is also described for protecting one or more batteries of the device from an over-current situation.

Abstract: A method of making a pressurized packaged liquid beverage including filling a container including a one-way valve with a liquid mixture including a base liquid and a gum; sealing the container; introducing a volume of gas through the one-way valve after sealing the container; and agitating the container. When the container is opened, the liquid mixture increases in volume and separates into a liquid phase and a drinkable foam phase, which may persist for an extended period of time. The base liquid includes milk, coffee, fruit juice, or mixtures thereof.

Abstract: An example of a technique for compensating for effects of Earth's magnetic field variations on a mobile device positioning system. A mobile device utilizes a compass to obtain an absolute heading when located relative to a visible light source. The mobile device obtains a heading correction value based on an identifier of the visible light source. An orientation of a map displayed on the mobile device is rotated based on the absolute heading and the heading correction value in order to provide an indication of a location of the mobile device properly oriented on the map.

Abstract: An example of a technique for maintaining a previously calibrated mobile device positioning system to account for changes in perturbers of the Earth's magnetic field. A mobile device obtains a corrected heading estimate of the mobile device within a space based on a previously recorded heading correction value. The mobile device also calculates a device heading relative to a previously orientated map of the space. The mobile device subsequently updates the heading correction value with any deviation between the corrected heading estimate and the calculated device heading.
