An apparatus, system and method are disclosed for photographing an image in a photo booth employing a light-emitting backdrop. For example, the apparatus comprises a photo booth including a housing having an entrance on one side with movable closure member to minimize encroachment of exterior light, a seat, a first white light source facing the subject(s) for emitting a first selected light intensity upon the subjects, a second white light emitting source facing generally the rear of the subject(s) so as to provide a light-emitting photographic backdrop, and a device for receiving a selected form of payment, or alternatively, for activating the apparatus without payment. In addition, the apparatus includes a photography unit comprising a selected camera, a program-controlled apparatus, a printer, and the first light source, for taking a digital photograph of objects within a selected frame of reference.

A distributed digital communications network and method for interactive communications, e.g., for cellular, wireless Internet access, digital television, and/or like multimedia services, is provided, that includes one or more global communications satellites positioned and adapted for receiving and relaying packet data communications encapsulating the interactive communications. One or more base station(s) are located in each of a plurality of selected remote geographic regions, and have mobile wireless links to a plurality of subscribers of communications services in the region. A plurality of satellite communications terminals is also provided for communicating with the satellite from the region. Each terminal is located in the selected remote geographic region and associated with one or more of the base stations. In addition, a plurality of user terminals are utilized, each located in the selected remote geographic region and associated with the base station(s) in the region. One or more base station controller(s) located remotely from, or locally with, the base station(s) have programming for controlling the base stations. Furthermore, a single mobile switching center located remotely from, or locally with, the base station controller(s) and the base stations. The switching center, in addition, has a digital communications signal processor for handling digital signal switching between the plurality of base stations, and/or wireline and/or other communications network(s). Finally, a packet data network is utilized between the satellite and satellite communications terminals for interactive data communications throughout the distributed network.

An electronic keyboard instrument is provided and methods of playing and assembling the same. The instrument comprises a controller for enabling activation of electronic signals having audible, visible, amplifiable, recordable and/or like characteristics, and a power source for operating the controller. A first keyboard is provided having a first selected length and being oriented in a first direction such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a first hand of one or more users. A second keyboard with a second selected length is generally coextensive with and oriented generally opposite to the first such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a second hand of the one or more users. In addition, an interface connects the controller to at least one external device having sound module, and/or sequencing and signal enhancement functions. A plurality of peripheral devices operatively connected thereto permit interactive control and manipulation of the signals. Finally, a wearable support is mounted to the instrument for suspending the first and second keyboards from the user's body during instrument operation. Alternatively, the instrument is suspended by a support structure in a generally horizontal fashion for simultaneous operation by multiple users.

A device is provided for releasing a spear shaft of a spear gun for scuba diving or the like. The shaft has a latch element formed on a first lever pivotally connected at its front end to a screw attached to and integrally with a frame of the gun, the lever being maintained elastically in a resting position. The gun has a trigger with an abutment portion forced elastically against the front end of the first lever extending forward of a convex upper surface. The convex upper surface intersects a concave surface at an edge that traces a first circular trajectory when the trigger is rotated. A second lever is rotatably connected to the frame, the front end of the second lever being movable along a second circular trajectory intersecting the first circular trajectory. An arm of the second lever extends so as to intersect the trajectory of the spear shaft when it is loaded in the gun, such that the shaft abuts the latch element first, thereby moving the first lever away from its resting position, until it engages a shaped cavity of the shaft, and subsequently abuts the arm of the second lever. This causes the second lever to turn until it abuts the first lever in line with the latch element, simultaneously raising its front end up to and against the convex surface of the trigger. The front end of the first lever is slidingly connected to a screw, such that the first lever may be variably displaced, thereby adjusting the force applied by the second lever to the trigger.

A bi-material, anti-dazzle raster for tubular light sources includes, for example, at least two side pieces and a plurality of transverse partitions that extend between the pieces. The side pieces are made of a relatively rigid and resistant material and the partitions are grouped into modular units. Each unit includes a selected number of partitions connected to one another by at least two generally parallel connection bars and to the side pieces by a snap fit. The modular units are formed of a selected plastic material using injection molding.

A swimming flipper comprising a blade (1) made of relatively rigid material, a shoe (2) made of relatively yielding material and at least a pair of lateral ribs (3) extending along the edges of the blade. On the blade there are provided at least two longitudinal slots (9) arranged symmetrically with respect to the longitudinal axis of the flipper and two openings (11) extending diagonally from the shoe towards the lateral edges of the blade. The slots and the openings are filled with a relatively yielding material in the form of flattened ribs (12, 13).
摘要:
A method is disclosed for amortizing the authentication overhead of data transmissions. The method comprises establishing a first secure transmission of data between a transmitter and a receiver by transmitting at least one token to the receiver during the first secure transmission. There may be any number of senders and receivers, and any receivers may be a sender and vice versa. The method also comprises establishing at least one additional transmission of data between the sender and the receiver and transmitting the data and at least one token during the at least one additional transmission. In addition, the method compares the at least one token transmitted during the at least one additional transmission to the token transmitted during the first secure transmission to guarantee the authenticity of that at least one additional transmission.The method may also include transmitting a preselected number of tokens during the first secure transmission. The number of additional transmissions may or may not correspond to the preselected number of tokens. The at least one additional transmission may be conducted over an unsecure connection using open communication. The first secure transmission may be protected or encrypted.
