Abstract:
An ostomy bag (1) for receiving bodily waste comprising; an outer protective pouch (3) comprising a laminated material with an outer layer of water-impermeable material (15) and an inner layer of water-soluble material (13); an inner waste-collecting pouch (5) enclosed within the outer protective pouch (3) comprising a laminated material with an outer layer of water-soluble material (9) and an inner layer of water-impermeable material (7), and means (23) defining an orifice (19) to enable bodily waste to enter the inner pouch (5); wherein the outer protective pouch (3) is removeably sealed and both the outer protective pouch (3) and inner waste-collecting pouch (5) are of a structure which is weakened upon immersion in a toilet bowl to both become less buoyant such that the bag (1) can be flushed away.
Abstract:
A tube holder (1) for removeably securing a tube (19) to the skin of a patient comprising a plastics film (3) bonded to an adhesive material on a bodyside surface of the film (3); and a separate first (7,9) and second means for applying pressure to a tube (19) located in the holder (1) during use, wherein the first (7,9) and second means are bonded to a tube-side surface of the plastics film (3) and pressure can be applied, in use, to at least two opposing sides of the tube (19).
Abstract:
One version of this disclosure includes a system for assigning an elevator car to respond to a call signal wherein a controller is responsible for determining which elevator car will respond to a call signal. This version includes the controller receiving a hall call signal, receiving information regarding the elevator system, determining whether the call assignment can be made in view of a first rule associated with a banned call assignment, and eliminating the rule against banned call assignments when necessary to avoid saturation of the elevator system.
Abstract:
An Internet protocol (IP) packet switching communication system using real time transport protocol (RTP). Control packets map group identification codes to a multicast address on a network. Control packets are distributed on the network using simple object access protocol (SOAP) messages with extensible markup language (XML) payloads. Mapping may include dynamic or static functions. Multicast address data is distributed among routers. A message from a caller is multicast by the routers, based on the multicast address, to one or more destinations.
Abstract:
An improved system of variable speed drives that enhances the energy efficiency of an elevator system by enabling power transfer between the variable speed drives of two or more elevators via a common DC bus. Any combination of regenerative and non-regenerative variable speed drives may be used with the present invention. Energy storage devices may be connected to the common DC bus further improve efficiency.
Abstract:
An elevator system comprises at least two independently operable elevator cars in each of a plurality of elevator shafts within a building. The elevator system comprises at least one first elevator shaft having a lower first and a lower second region, where a first elevator car moves within the lower first region of the first elevator shaft and a second elevator car moves within the lower second region. The first and second elevators are moveably controlled independently of each other within the first shaft. The system also includes at least one second elevator shaft having an upper first and an upper second region, where a third elevator car moves within the upper first region of the second elevator shaft and a fourth elevator car moving within the upper second region. The third and fourth elevator cars also are moveably controlled independently of each other.
Abstract:
A synthetic rope for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands forming layers of the rope, each strand formed from a plurality of pre-twisted strands made from high modulus synthetic filaments. One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.
Abstract:
An elevator control system to govern elevator movement to avoid or minimize passenger discomfort caused by pressure changes associated with an elevator's movement and to optimize elevator operation. In one exemplary embodiment, the system uses the passenger's natural relief which occurs while the elevator car is stopped to reduce the pressure difference experienced by the passengers' ears as a factor to optimally control the operation of the elevator. In another example, the system obtains input regarding the traveling speed and conditions of the elevator system. This system then simulates individual trips for passengers that includes monitoring the pressure changes being experienced by passengers throughout the elevator's travels in order to ensure that the pressure differential level for each passenger remains below a designated maximum comfortable and safe level. This system uses the parameters of a successful simulation to govern the actual operation of the elevators.
Abstract:
One embodiment disclosed comprises a roller guide device comprising at least one roller and a respective braking apparatus for the roller. The braking apparatus in this embodiment comprises a disc brake. In this same embodiment, the disc brake performs a braking operation by pressing a pair of pads on both sides of a roller. The disc brake may be supported by the base of the roller guide device, and comprise a single-piston mechanism that affects movement of the pair of pads.
Abstract:
The systems and methods of present invention invoke an elevator communication system for providing communication between a plurality of hall fixture devices and at least one elevator system controller. The elevator communication system includes at least one elevator door interlock wiring circuit, which has a first and a second portion. A first transceiver device is coupled to the first portion of the door interlock wiring for transmitting and receiving signals between the at least one elevator system controller and the plurality of hall fixture devices over the interlock wiring. A second transceiver device is coupled to the second portion of the door interlock wiring for transmitting and receiving the signals between the at least one elevator system controller and the plurality of hall fixture devices over the interlock wiring.
