Abstract: A patient support, such as a hospital bed, provided with a control circuit comprising a controller, memory, a communication interface, and a processor. The memory stores data related to the patient support. The controller includes a port, such as a USB port, or similar device, for providing an encryption key to the controller memory. The processor outputs data only when an encryption key is present in the memory. Before outputting in data, the processor may encrypt and/or digitally sign the data using the key. The outputting of data may be in response to an encrypted and/or digitally signed request.

Abstract: An aircraft engine assembly including an engine, an engine suspension pylon, and a heat exchanger system including a second outlet located between the box and the engine, aft from the aft engine suspension. Furthermore, the exchanger in the heat exchanger system is at least partially arranged inside an aft aerodynamic fairing of the suspension pylon, the aft aerodynamic fairing being located entirely aft from the aft engine suspension.

Abstract: An aircraft engine assembly including an engine, an engine suspension pylon, and a heat exchanger system including an outlet located between the box and the engine, aft from the aft engine suspension. Furthermore, the outlet of the heat exchanger system is provided on an outlet pipe connected to the exchanger and passing through a structural block fixed on a box, between the box and the engine.

Abstract: A method of facilitating online group play of a lottery game. Lottery players each having their own personal profile are permitted to join an online lottery group by linking their personal profile with the lottery group profile. The lottery group is administered by one of the group members. Group members are able to purchase lottery tickets online using personal financial information, such as a credit card number, stored in their personal profile and are able to ascribe the purchased lottery tickets to the group. Group members are able to view the numbers of tickets ascribed to the group and are able to communicate with one another using a message posting means viewable only by group members. Group members are notified electronically in the event that one of the tickets ascribed to the group is a winning ticket. The method facilitates the keeping of electronic records of which group members are playing in any particular draw, reducing the likelihood of a future dispute over attribution of any group winnings.

Abstract: A solar energy collector comprising a plurality of three-dimensional elements having substantially the same general configuration. Each of the elements has a substantially circular base and the elements are nested within one another so as to form the energy collector.
