Abstract: A controller can be configured to control a system for extracting liquid water from air comprising a thermal unit, a primary desiccant wheel, and a regeneration fluid path. The controller can comprise a sensor, a motor, and a microcontroller coupled to the sensor and the motor. The microcontroller can be configured to determine a water extraction efficiency based on at least one signal received from the sensor, and also can be configured to maximize the water extraction efficiency by adjusting a speed of the motor in response to the determined water extraction efficiency.

Abstract: Disclosed is a system for customizing protections provided to different application programming interfaces (“APIs”) and different functions of an API based on different API context and user context associated with the different APIs and the different functions of each API. The system receives a particular API, determines API context for proper usage of one or more functions of the particular API, and determines user context associated with endpoints properly accessing the one or more functions. The system generates a model for differentiating between proper and improper use of the one or more functions based on contextual relationships between different combinations of the API context and the user context. The system monitors usage of the one or more functions based on the model, and performs an action that is associated with the model in response to the usage violating the contextual relationships for the one or more functions.

Abstract: A method of mounting rotary scale member on machine part includes: locating rotary scale member on machine part such that scale axis and axis of rotation are substantially parallel, and subsequently arranging at least a first radial adjustment device to contact both machine part and rotary scale member, and manipulating the at least first radial adjustment device to radially displace body of rotary scale member. At least the majority of any radial reaction force, generated as a result of the interaction of at least one of the flexures with a radial stop member against which it is radially pressed, and which is imparted on the at least first radial adjustment device by rotary scale member in opposition to the radial displacement of the rotary scale member, is directed into, and reacted by, the machine part via the contact between the at least first radial adjustment device and the machine part.

The drive unit is controlled by a control unit (ECU) which controls the movement of the driven roller (15) between the disengaged position and the engaged position and also controls the rotation (and direction) of the driven roller (15). The caravan mover (10) of the present invention includes an integral power supply such that the unit comprises a single integral system which is easily installed on the caravan and does not require the routing of cables from a remote power supply.

Abstract: The present invention relates to an adjustable control system for a caravan moving system in which the caravan movers each include a brushed motor. The adjustable control system can control two caravan movers (10) mounted on a single axle caravan or two caravan movers mounted on a twin axle caravan or four caravan movers mounted on a twin axle caravan (quad system). The caravan moving system comprises a control unit, a user operated actuating device, power means and a drive unit. The present invention utilises a control system which provides variable movement of the or each caravan mover (10) and also provides gradual changes in both speed of each brushed motor and the subsequent ability to smoothly change the direction of travel of the caravan. In particular, the present invention enables the caravan to follow a wavy or curved line of travel in which the radius of the turn varies (i.e. from 0 degrees to a spin on the spot (equivalent to a 90 degree turn)).

Abstract: The present invention relates to a trailer drive unit in the form of a caravan mover comprising a motor 16 (drive means/drive device), a head 14 housing a roller 20 which are linked together by a gear mechanism 22. Specifically, the present invention provides a support and drive transmission system 22 located centrally on the roller 20 with the roller 20 being provided by a first lateral portion/roller 19 and a second lateral portion/roller 21. In this arrangement, the length of the lateral roller 10 portions 19, 21 are individually shorter than a single roller such that the torque created in the central drive transmission portion is significantly less.

Abstract: The invention provides a method and apparatus for managing operation of a spanning tree protocol process in a network bridge. This comprises setting the network bridge to either an active mode or a defer mode in which a spanning tree protocol process is not run in response to a triggering event. The system remains in the defer mode for a period of time in which no further operations of the state machines will take place, before reverting to the active mode and normal processing of triggering events is carried out.

The spanning tree protocol process comprises a plurality of state machines including a Port Information state machine. The Port Information state machine comprises an UPDATE state and a plurality of other states. The invention involves running a Protocol Manager on a central controller, wherein the Protocol Manager owns the UPDATE state such that updates are carried out by the Protocol Manager. The Neighbor Managers on each of the port controllers owns the plurality of other states of the Port Information state machine, such that updates are carried out by the respective Neighbor Manager on said port controller. This allows the Protocol Manager and the Neighbor Managers to operate without having to force one to pause whilst work is done on the other.

Abstract: Measures for transferring routing protocol information between a software defined network and one or more external networks are provided. A control node in a software defined network (SDN) is configured to maintain a protocol information database comprising routing protocol information for one or more switching nodes in the SDN. In response to detecting occurrence of a predetermined trigger event, the control node modifies the routing protocol information in the protocol information database, and determines whether the one or more switching nodes include an edge switching node. In response to the determination, a routing protocol message is transmitted from the control node to the edge switching node for forwarding via an external network interface. The routing protocol message includes data generated on the basis of the modified routing protocol information.

Abstract: A method of determining radiation exposure during a criticality excursion of a dosimeter having at least one fluorescent nuclear track detector (FNTD) element includes determining the power spectrum integral (PSI) value of the fluorescent images obtained from FNTD element at each of a plurality of different depths using laser induced fluorescent microscopy; normalizing the depth profile to the shallowest depth; fitting a double exponential function to the normalized depth profile; determining the median neutron energy from the E=f(1/e) function; and determining a neutron energy dose correction factor (NCF) from the NCF=f(E) function. The neutron dose, D, can then be calculated by dividing absolute value of the neutron-induced PSI by a sensitivity factor S and multiplying it by the neutron energy dose correction factor NCF.
