摘要:
A system for controlling a roller shade having a roller tube windingly receiving a shade fabric varies roller tube rotational speed for constant linear shade speed. The desired linear shade speed, roller tube diameter and shade fabric thickness and length are stored in a memory for use by a microprocessor. Preferably, the roller tube rotational speed is varied by the microprocessor depending on shade position determined by signals from Hall effect sensors. The microprocessor maintains a counter number that is increased or decreased depending on direction of rotation. Based on the counter number, the microprocessor determines shade position and a corrected rotational speed for the desired linear shade speed. Preferably, the microprocessor controls roller tube rotational speed using a pulse width modulated signal. The system may be used to control first and second roller shades having roller tubes of differing diameters or shade fabrics of varying thicknesses.

摘要:
A wireless access point may be in the form of a femtocell basestation in a cellular network. In order to establish a connection into the cellular network, an identity token is required for authorisation. A remote service, accessible over a Wide Area Network such as the interne, can register with the access point. When a connected user attempts to connect to the remote service, information derived from the identity token is inserted into the data traffic. Where the identity token identifies the access point, the remote service can return location-specific information. Where the identity token identifies the connected user, the remote service can return subscriber-specific information. The access point can insert information derived directly from the identity token, or it can use the identity token to access a service identity registry, and can then insert the service identity into the data traffic.

A safety circuit for use in low-voltage systems improves safety of and additional features to low-voltage connections. When incorporated into a battery, the circuit leaves the battery disconnected from the low-voltage system until it determines that it is safe to make a connection. When the safety circuit determines that no unsafe conditions exist and that it is safe to connect the battery, the safety circuit may connect the battery by way of a “soft start” that provides a connection over a period of time that reduces or prevents inductive voltage spikes on the low-voltage system. A method is used for detection of proper polarity of the connections between the battery and the low-voltage system. When incorporated into a jumper cable, the safety circuit provides communication abilities, can provide test abilities, and improves connection safety and functionality, such as allowing transfer of power between low-voltage systems having different voltages.

A process for the preparation of a water-dissipatable polyurethane comprising preparation of a polyurethane prepolymer, reacting the polyurethane prepolymer with a mono functional end-capping agent to give a partially end capped polyurethane prepolymer and chain extending the partially end capped polyurethane prepolymer to give the water-dissipatable polyurethane. The polyurethanes are useful in ink jet printing.

The present invention comprises a brake monitoring system. The monitoring system includes an auxiliary braking device, the auxiliary braking device configured to activate a braking system of a towed vehicle. The monitoring system also includes a transmitter unit including a transmitter, the transmitter configured to transmit a signal indicating that the braking system of the towed vehicle has been activated. A receiver unit is also included. The receiver unit includes a receiver, the receiver configured to receive the signal transmitted by the transmitter. The monitoring system also includes an indicator in communication with the receiver unit. Activation of the indicator informs a driver of a towing vehicle that the braking system of the towed vehicle has been activated.

Provided herein is a system including, in some embodiments, a user-interaction module and a sponsor module of at least one mobile computing device. The user-interaction module can be configured to display on a touchscreen display screen of the device moment-related information corresponding to one or more moments in a performance of an entity, an occurrence of an event, or a combination thereof, the one or more moments selected from server-auctioned future moments, present moments, and past moments. The user-interaction module can also be configured to display user-interaction information configured to facilitate user interaction with the one or more server-auctioned moments on the display screen of the device. The sponsor module can be configured to display one or more sponsors of the performance of the entity, the occurrence of the event, or the combination thereof during the one or more server-auctioned moments on the display screen of the device.
