Abstract: A network based system and method for managing inventory is disclosed. A smartphone device is connected to a portable barcode scanner using a communication connection. A scanner adapter application on the smartphone device receives output date comprising order data, and parses the order data, passing it to an upload application. The smartphone device further comprises an order management application to take order data from the scanner adapter application and smartphone user data entry to access a backend server system to retrieve and collect detailed order data in support of order submission. The detailed order data contains data elements necessary for completion and submission of orders. An API configured to receive the at least part of the order data from the upload application processes the order information into an electronic order, and sends the electronic order to a vendor server.

Abstract: Distributed communications systems providing and supporting radio frequency (RF) communication services and digital data services, and related components and methods are disclosed. The RF communication services can be distributed over optical fiber to client devices, such as remote units for example. Power can also be distributed over electrical medium that is provided to distribute digital data services, if desired, to provide power to remote communications devices and/or client devices coupled to the remote communications devices for operation. In this manner, as an example, the same electrical medium used to transport digital data signals in the distributed antenna system can also be employed to provide power to the remote communications devices and/or client devices coupled to the remote communications devices.

Abstract: Unified optical fiber-based distributed antenna systems (DASs) for supporting small cell communications deployment from multiple small cell service providers are disclosed. The unified optical fiber-based DASs disclosed herein are configured to receive multiple small cell communications from different small cell service providers to be deployed over optical fiber to small cells in the DAS. In this manner, the same DAS architecture can be employed to distribute different small cell communications from different small cell service providers to small cells. Use of optical fiber for delivering small cell communications can reduce the risk of having to deploy new cabling if bandwidth needs for future small cell communication services exceeds conductive wiring capabilities. Optical fiber cabling can also allow for higher distance cable runs to the small cells due to the lower loss of optical fiber, which can provide for enhanced centralization services.

Abstract: Simulating sector changes in an application module (AM) in a wireless communications system (WCS) to simulate site walks in the WCS. The AMs are wireless telecommunication circuitry wired or wirelessly associated with wireless communications system components in a WCS. In one embodiment, the AMs are configured to determine signal information (e.g., signal strength, power and/or quality) of live communications signals in a WCS. The measured signal strength values are then artificially changed to simulate a site walk in the WCS. For example, the signal strength of communication signals received by an AM from a particular sector can be artificially lowered so that the signal strength from a neighboring sector located further away from the AM appears to be stronger. In this manner, a site walk of the AM in the sectors in which communications signals are received by the AM in the WCS can be simulated.

Abstract: A combination of capillary forces and gas pressure is used to control the movement of liquid samples within a microfluidic device. A liquid sample introduced to a proximal portion of a capillary channel of a microfluidic device moves by capillary action partway along the capillary channel. As the liquid sample moves, a pressure of a gas acting upon a distal gas-liquid interface of the liquid sample increases by an amount sufficient to stop further movement of the liquid sample. To initiate further movement of the liquid sample, a pump connected to a distal portion of the capillary channel decreases the pressure of the gas acting upon the distal gas-liquid interface of the liquid sample by an amount sufficient to permit the liquid sample to move by capillary action further along the capillary channel of the microfluidic device.

Abstract: In example methods and systems described, insulin therapy for a patient can be determined. At least one of a short-acting subcutaneous insulin dosage recommendation, a correction subcutaneous insulin dosage recommendation, an intravenous insulin dosage recommendation, a recommended amount of carbohydrates to be administered to the patient, or combinations thereof, can be determined. In addition, information indicating a confirmation of a nutrition intake for the patient, and a long-acting insulin-on-board for the patient can be received, and based on this information, a required long-acting subcutaneous or intravenous insulin dosage for the patient can be determined. The short-acting subcutaneous or intravenous insulin dosage recommendation can be adjusted based, at least in part, on a difference between the long-acting insulin-on-board and the required long-acting subcutaneous or intravenous insulin dosage.

The input motor may have a rotation axis, a substantially flat surface, and a rounded protrusion extending from the flat surface.

Abstract: An elliptically interfacing gear assisted braking system may include an input shaft with a coupled input gear, a wobble plate, a rotor with a reaction gear, and an actuated brake mechanism, or brake. The input shaft may define an axis of rotation and the wobble plate may have a wobble axis disposed at a non-zero angle relative to the rotation axis. A set of face teeth disposed on one surface of the wobble plate may partially mesh with the input gear, and a set of wobble teeth on an opposite surface of the wobble plate may partially mesh with the reaction gear. Rotation of the input shaft may thereby cause rotation of the wobble plate and rotor. The brake may mate with the rotor and when actuated, slow the rotor with respect to the input shaft. Rolling contact forces between the surfaces of the wobble teeth and reaction teeth may then induce nutation in the wobble plate, thereby dissipating rotational energy.

For example, the signal strength of communication signals received by an AM from a particular sector can be artificially lowered so that the signal strength from a neighboring sector located further away from the AM appears to be stronger. In this manner, a site walk of the AM in the sectors in which communications signals are received by the AM in the WCS can be simulated.
