    Abstract: Provided is a ventilator that includes a breathing system, a mechanical system coupled to breathing system, and a control system coupled to breathing system and mechanical system. The control system includes pressure sensors, processing circuitry, and memory configured to store a look-up table. The processing circuitry receives a set of values for plurality of parameters, identifies a compression value from a plurality of compression values in the look-up table based on the received set of values. The processing circuitry causes the mechanical system to compress a bag valve of the breathing system in accordance with the identified compression value. The compression of the bag valve causes a gaseous inhalant to flow through the breathing system within a time-interval. The processing circuitry determines an actual volume of the gaseous inhalant and iteratively modifies the compression value of the bag valve to match a desired volume of the gaseous inhalant.

    Abstract: A method of attaching and detaching objects allowing for rotation wherein protrusions built in or attached to one object are forced into cavity sockets built in or attached to another by causing force resulting in momentary bending of protrusions or the cavities. The sequential bending causes curvilinear motion allowing protrusions to enter otherwise inaccessible cavity sockets. Once in, the components of the joining mechanism revert to natural position and an equilibrium is reached which keeps the objects attached, yet free to move around an axis. This equilibrium can only be disturbed by causing force at specific points on the mechanism and pulling the objects apart in a curvilinear motion, thereby detaching the objects in one continuous motion with little effort. Objects not permitting momentary bending can be attached with the mechanism housed in a casing. Permitted angles of rotation are controllable and attached objects can be locked in a position.

    Abstract: A safety intravenous cannula and catheter device is disclosed. The device permits easy insertion of a cannula made of a biocompatible material into the vein with a guide needle and withdrawal of the guide needle into a safety chamber with an in- built locking mechanism with completely prevents removal and/reuse of the needle. The needle before insertion is protected by a biocompatible sheath which when inserted into the vein and after withdrawal of the needle acts as catheter. Similarly, after withdrawal the needle is locked inside a safety chamber in such a manner that at no time does the user come into contact with the needle or in any danger of accidental injury.

    Abstract: In one example, a serving gateway device includes one or more network interfaces configured to receive a packet fragment from a packet data network gateway (PGW) device, and a control unit configured to hash a source Internet protocol (IP) address, a destination IP address, and a fragment identifier value for the packet fragment to determine an entry of a hash table, wherein the entry of the hash table includes data defining a next expected offset, a next expected fragment identifier, and a reference to a fragment table comprising data for at least one previous packet fragment corresponding to the packet fragment, to compare a length of the packet fragment to the next expected offset and the fragment identifier value for the packet fragment to the next expected fragment identifier, and store the packet fragment using the fragment table based on the comparison.

    Abstract: A comparison circuit for detecting impedance mismatch between pull-up and pull-down devices in a circuit to be monitored includes a comparator operative to receive first and second signals and to generate, as an output, a third signal indicative of a difference between the first and second signals. A first signal generator is operative to generate the first signal indicative of a difference between reference pull-up and pull-down currents that is scaled by a prescribed amount. The reference pull-up current is indicative of a current flowing through at least one corresponding pull-up transistor device in the circuit to be monitored. The pull-down reference current is indicative of a current flowing through at least one corresponding pull-down transistor device in the circuit to be monitored. A second signal generator connected with the second input of the comparator is operative to generate the second signal as a reference voltage defining a prescribed impedance mismatch threshold associated with the circuit to be monitored.
