Abstract: An advanced technology frame structure is described herein. The advanced technology frame structure can enhance a first technology frame structure in dimensions of time, frequency, or a combination of time and frequency. A second technology frame structure time division multiplexes second technology subframes with the first technology downlink and uplink subframes. The first technology downlink subframe can be divided into a first technology downlink subframe and one or more second technology downlink subframes. Similarly, the first technology uplink subframe can be divided into a first uplink subframe and one or more second technology uplink subframes. These principles can be expanded upon and can be applied in many communication systems.

Abstract: For an example embodiment, a method for a communication device operating in a synchronous communication system is described. The method includes performing a listen-before-talk (LBT) procedure prior to the start of a downlink subframe of a synchronous frame and determining if a transmission from another communication device of another communication system is detected during the LBT procedure. In the case that a transmission is detected during the LBT procedure, the communication device refrains from transmitting during the downlink subframe. In the case that a transmission is not detected during the LBT procedure, the communication device transmits during the downlink subframe.

Abstract: A vehicle (2), comprising: pressure detection means (16), vehicle stabilizing means (18); means (14) for receiving an input from the pressure detection means (16), in response to the pressure detection means (16) detecting an increase in pressure caused by an explosion; and control means (12) for controlling, in response to reception of the input from the pressure detecting means (16), the vehicle stabilizing means (18) to apply a force to the vehicle (2), in order to stabilize the vehicle (2) in response to the explosion.

Abstract: An audio device has passive radiators that are driven by acoustic drivers. The passive radiators are arranged so that the net mechanical vibration is minimized.

Abstract: An advertising display apparatus comprising a hollow receiving tube with an essentially closed distal end and an essentially open proximal end enclosed within a base region, means for retaining a preprinted material inserted through said base region, wherein the hollow receiving tube comprises a plurality of faces where at least one face is transparent and through which said preprinted material may be viewed. The plurality of faces comprising the hollow receiving tube are preferably of a convex shape. Included within the base region is a retention lip which extends into and partially occludes the essentially open proximal end of the hollow receiving tube. The base region may include additional fitments to allow for attachment of the display apparatus to surfaces not of a flat horizontal orientation. The base region may further include means for producing light or sound.

Abstract: A flexure includes a shaped sheet of material having a middle portion coupled to a magnet, an end portion, and a corner portion between the end portion and the middle portion, the corner portion including a curve with a concave curvature relative to a point of view outside the corner portion. The flexure may be used in a linear motor.

Abstract: An acoustic passive radiator that controls “rocking mode” vibration. An acoustic passive radiator includes a diaphragm for radiating acoustic energy. The diaphragm has a perimeter portion and a central portion. The perimeter portion is thicker than the central portion. The passive radiator further includes a passive radiator suspension. The suspension includes a skin element encasing the diaphragm. The skin element comprises a surround for physically coupling the passive radiator to an acoustic enclosure, pneumatically sealing the diaphragm and the enclosure. The surround has a non-uniform width. The passive radiator a non-pneumatically sealing, non-surround, non-spider suspension element. The non-surround suspension element and the surround coact to control the motion of the diaphragm and to support the weight of the diaphragm.

The hollow receiving tube in conjunction with the essentially closed distal end and the proximal base end act to retain the preprinted material in a protected environment which aids in ensuring a clean, quality representation of the preprinted material for protracted time periods, especially in environments where people may come into repeated contact with the display apparatus and it is desirable to maintain the quality of the preprinted material, such as restaurants, trade shows and retail sales stores.

Abstract: An electromagnetic actuator includes a stator assembly mounted to a center pole formed of material having high magnetic permeability and functions as a return path for the magnetic field generated when current is passed through coils in the stator assembly. When current is applied to one or more coils within the stator assembly, a magnetic field is generated that interacts with a magnetic field generated by one or more magnets disposed within the armature assembly and causes the armature to move relative to the center pole thus, for example, opening or closing a valve.
