Abstract:
Examples of a wave simulator for board sports and other uses are disclosed. An example wave simulator includes means for forming a wave, the means having at least one inclined side wall and a bottom corresponding to a desired wave shape. The wave simulator includes means for flowing water along at least partially along the inclined side wall and bottom of the flume to form a simulated wave. The wave simulator includes means for restraining a board rider in the means for forming a wave. Streamlines of the simulated wave are substantially parallel to a crest line of the simulated wave, and an inclined water flow ends in a downward arc.
Abstract:
A method of determining an estimated leak flow Qest in a gas delivery system is provided that includes determining for each of N breaths (N>1): (i) an average total flow Formula (I) of the gas delivery system, and (ii) M values of Formula (II) (M>1) using M γ values, wherein each P is a leak pressure of the gas delivery system and each γ value is an integer or non-integer real number, determining which one of the γ values results in a minimum variation of the values of a coefficient g over the N breaths, wherein for each breath and each γ value the coefficient g is determined by Formula and determining the estimated leak flow Qest using at least the determined one of the γ values.
Abstract:
A system and method for delivering a flow of gas to an airway of a patient (54). The system includes a gas flow generator (52) and a patient circuit (56) comprising a conduit (100) that communicates the flow of gas to a patient. A sensor (62) is configured to measure a rate of the flow gas and generate flow signals based on the measured rate of flow. A controller (64) is operatively connected with the gas flow generator (52) and the sensor (62) and is configured to control a pressure of the flow of gas provided to the patient. The controller (64) receives the flow signals from the sensor (62), determines a rate of change in the flow of the gas, and modifies or compensates the pressure of the flow of gas provided to the patient if the rate of change in the flow of gas provided to the patient exceeds a threshold amount.
Abstract:
A clip for securing a flexible armored cable to a structural object. The clip including a longitudinally extending clip body having a generally C-shaped wire receiving cavity extending in the longitudinal direction and about a cavity axis with a longitudinally extending cable receiving slot. The wire receiving cavity having a plurality of transverse ribs that are parallel to one another wherein each of the ribs has a first end and a second end that are circumferentially space about the cavity axis and which are longitudinally spaced. The ribs being configured to extend into a portion of a trough in the armored cable.
Abstract:
A touch system comprises a large scale touch surface on which an image is presented and at least two imaging devices looking across the touch surface and having overlapping fields of view. Processing structure communicates with the imaging devices and processes image data acquired by the imaging devices to determine pointer contacts on the touch surface using triangulation. The processing structure further executes at least one application to facilitate user interaction with the touch surface. Methods of interacting with the touch surface are also disclosed
Abstract:
A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.
Abstract:
A deflection member comprising a patterned framework having a web-side and a backside opposite to the web-side and forming an X-Y plane. The framework comprises a plurality of bases extending from the X-Y plane in a Z-direction perpendicular to the X-Y plane, and a plurality of suspended portions laterally extending from the plurality of bases to form void spaces between the X-Y plane and the suspended portions. The deflection member can comprise a reinforcing element joined to the plurality of bases and positioned between the web-side and at least a portion of the backside of the framework. A process for making the deflection member comprises curing a coating of a liquid photosensitive resin supported by a forming surface through a mask having a pattern of transparent and opaque regions. The opaque regions comprise regions having first opacity and regions having second opacity less than the first opacity. The transparent regions leave coating's areas corresponding thereto unshielded to allow said areas to cure through the entire thickness of the coating, thereby forming the bases. The opaque regions having the first opacity shield first areas of the coating to preclude curing thereof through the entire thickness of the coating. The opaque regions having the second opacity partially shield second areas of the coating to allow them to cure through a predetermined second thickness less than the entire thickness of the coating, thereby forming the suspended portions. The mask can have a gradient opacity that gradually changes in at least one direction to cause the coating to cure though a differential thickness. The mask can also have a three-dimensional topography pattern therein to imprint the coating.
Abstract:
An improved method for bonding webs. The method includes overlapping two webs, slitting the two webs, reoverlapping the two webs and bonding the two webs together. The steps of reoverlapping the two webs may be accomplished with a number of different types of devices including but not limited to: a bumpered roll, a notched roll, a crowned roll, a bowed roll, an out of plane roll, and variable speed rolls.
Abstract:
A system and method for preprocessing and delivering multimedia presentations to customers such that delays due to interactive response time is virtually eliminated include a preprocessor, mass storage, a delivery processor, a distribution network, and a plurality of presentation processors. The preprocessor receives as inputs an original multimedia presentation and parameters characterizing other system components, which parameters include the round trip latency between the delivery processor and a presentation processor, and generates a preprocessed multimedia presentation including a delivery schedule in the form of a labelled, directed graph. In generating the delivery schedule, the preprocessor ensures that each object of the presentation and its associated presentation command arrive at the presentation processor no later than its presentation time; objects and commands which are delivered to the presentation processor can be accommodated at the memory of the presentation processor; and those objects to be presented immediately in response to a customer's selection of an interactive feature are received at the presentation processor prior to their earliest presentation times. This delivery schedule contains delivery commands which are executed by the delivery processor for transmitting objects of the presentation and their associated presentation commands to the presentation processor, which executes the presentation commands and presents the objects to its corresponding customer.
