摘要:
Embodiments provide a sensor insertion tool (SIT) that provides a motive force for insertion of an analyte sensor into/through skin. A SIT may be releasably locked to one or more components of a sensor insertion system, such that components of the sensor insertion system remain securely coupled during sensor insertion. A SIT may include a release member that unlocks or uncouples the SIT and the other components after sensor insertion. In various embodiments, a SIT may be a component of a sensor insertion system configured for assembly by an end user, a health care professional, and/or a caretaker prior to sensor insertion, and may act in cooperation with other sensor insertion system components. Additional components and methods of assembly and use are also provided herein.

A method of in vivo conditioning of an indwelling sensor to reduce run-in time, (stabilization time) comprising: a) applying a first potential to the sensor and measuring a first current at the first potential; b) applying a second potential to the sensor and measuring a second current at the second potential; c) determining a relationship of the first current measured to the second current measured; repeating a, b, and c until the relationship between the first current measured and the second current measured has stabilized, thereby reducing sensor run-in time.

A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin. Such a device allows a sensor to penetrate mammalian skin without the use of an introducer device such as a needle. A device in accordance with embodiments of the present disclosure includes a housing for attachment to mammalian skin including an exit port for receiving the distal end of a biosensor and an injection activation device including a mechanism for forcing the sensing device from a first position within the housing, through the exit port to a second position, with sufficiently high velocity to partially penetrate the mammalian skin.

A system and method for charging batteries in a system wherein the output of the batteries is converted to alternating current utilizing inverters. The alternating current from the inverters is modified by transformers and variable speed drives to contain properties which enable the alternating current to be used in a power grid to operate conventional electrical appliances. At least two banks of batteries are employed in the system. A unique battery charging device is employed to maintain the two banks batteries in constant substantially full charge. The battery charging device switches between a charge mode for one bank of batteries and a rest mode for the other bank of batteries. The battery charging device constantly and rapidly switches the different banks of batteries between these two modes. A timer controls the amount of time that each mode is applied to each bank of batteries. A solar panel supplies electric power to the charging device to charge the batteries.

Embodiments herein provide an analyte sensor subassembly that provides an integrated structure enabling suitably secure electrical contact between an analyte sensor and the electronic components of an analyte sensor assembly. An analyte sensor subassembly assists the process of inserting the sensor into skin. An analyte sensor subassembly may operate in concert with one or more sensor insertion tools to provide insertion of an analyte sensor into the skin of a subject/patient. Associated devices, such as channel guides and sensor insertion tools, are also provided, as are methods of operation and sensor insertion.

The present invention relates to a scanning system optimized for lidar that includes a nodding mirror, a rotary electromagnetic drive, a rotary optical encoder, and control circuitry. The rotary electromagnetic drive includes a yoke incorporating a permanent magnet, and an arm having a coil at one end of the arm. The coil is enclosed within the yoke, and an opposite end of the arm is coupled to the nodding mirror, such that movement of the coil within the yoke in response to a current causes the nodding mirror to rotate. The rotary optical encoder produces an output signal in response to rotation of the nodding mirror, which serves as feedback to the control circuitry. The control circuitry adjusts the current provided to the rotary electromagnetic drive in response to the output signal, such that the nodding mirror rotates in a reference scan pattern.

Also disclosed are methods of producing an improved gypsum plaster including producing the disclosed powdered calcium sulfate hemihydrate [alpha-type] and mixing the powdered calcium sulfate hemihydrate [alpha-type] with water.
摘要:
Systems and techniques for command communication between wireless devices are described. In one implementation, a data gathering device (such as a continuous glucose monitor) and a monitoring/control device, which communicate data samples through a frequency hopping protocol, utilize a dedicated command frequency for the transmission of non-data instructions and acknowledgements. A command mode is described where the command frequency is regularly listened to by a device to determine if pairing or other instructions are being sent. In another example, when communications are disrupted or corrupted, the devices revert to using the command frequency in order to reacquire a paired link between the devices. The command frequency is also used for a flight mode, where the data-acquisition device goes into a low-, or no-power transmission mode and remains in the mode, storing sampled data, until instructed to leave the flight mode over the command frequency.

In accordance with a particular embodiment of the present invention, a method for producing a gypsum product includes providing a calcined gypsum powder. Water and an aqueous foam generated from a foaming agent comprising a first portion of sodium decyl sulfate are combined with the calcined gypsum powder to generate a foamed calcined gypsum slurry. The method may also include combining water, a foam generated from a first and second portion of the foaming agent, and the calcined gypsum powder. The second portion of the foaming agent may comprise ammonium decyl ether sulfate and ammonium octyl ether sulfate.
