Abstract: A recreational watercraft system of interconnectable, inflatable tubes that can incorporate a configurable frame that may be removably affixed at different vertical heights to attachment brackets that are axially strapped around the inflatable tubes. A plethora of accessories are available to accommodate, oars, paddles, masts, motors and the like, depending on what watercraft shape has been assembled. It can be assembled into a canoe, raft, motorboat, sailboat, fishing float etc.

Abstract: A frequency tuneable laser device includes a cavity mode selector and a cavity tuning arrangement. The cavity mode selector has a frequency response with a selection feature that is alignable in frequency with a selected cavity mode of the laser device. The cavity tuning arrangement includes a plurality of reflective elements arranged in optical series, and is used to adjust the effective optical path length of the laser cavity to move the cavity modes in frequency. The laser device further includes making the cavity mode selector and the cavity tuning arrangement perform a simultaneous coordinated movement such that respective frequencies of the selection feature and the selected cavity mode vary with substantially the same dependence on a parameter characterizing the simultaneous coordinated movement. For example, a periscope with a co-rotating etalon can be used to provide mode hop free tuning of the laser device.

Abstract: A sensor for attachment to an inflatable air cell cushion designed to detect optimal immersion of the cushion user into the in the inflatable cushion. The immersion depth of a user positioned on the cushion is determined by sensing air pressure in the cushion. The sensor accurately reads changes in pressure as air exits the cushion to allow an algorithm to determine optimal internal cushion pressure for a user.

Abstract: A fishing line tying tool designed to hold an eyelet bearing apparatus in its plier jaws and constrain two sections of fishing line, such that when the sections of line are brought together above the tool, can be quickly wound by rotation of a centralized post located at the bottom of the tool. There are a pair of opposing winder posts formed on the handle of the pliers that have two different sets of hooks for the retention of the fishing line thereon.

Abstract: An accessory for addition onto a floating pontoon style fishing craft that enables the occupant to safely stand while the craft is floating without fear of tipping the craft. This is in the form of a lowerable, retractable platform that resides below the waterline of the craft and also incorporates a removeable working table/safety bar that resides in front of the occupant's seat to constrain them from falling overboard and to allow them a stable work surface from which to perform fishing related activities. The retractable platform serves to allow the center of gravity of the occupant to remain in close proximity to the waterline of the craft thus preventing tipping. Because of the depth the platform projects beneath the craft, the position of the occupant's mass acts as a stabilizer or ballast rudder so as to let the occupant to safely cast his fishing line from the craft.

Abstract: A rotation detection kit, comprising: a beam source; a receiver comprising at least one beam intensity sensor; a polarizer device for location in the path of a beam emitted from the beam source and received by the beam sensor; and a modulator. The modulator is configured to modulate at least one of i) the beam source and ii) a beam emitted by the beam source to create a discretely varying polarization orientation thereby defining first and at least second temporally spaced beam portions. The temporally spaced beam portions are incident on the polarizer device and the beam sensor and have substantially identical profiles and at least an initial common propagation axis toward the polarizer device.

Abstract: Measurement apparatus comprising a laser measuring system an acoustic system is described. The apparatus provides a feedback control signal that can be used in the feedback control system of an associated machine. To allow real time, dynamic, operation the laser measurements are compensated using a compensation value derived from a plurality of laser measurements and at least one acoustic time of flight value.

Abstract: A localization process in a network of source devices and sink devices on a 1394 bus, is performed by a source device while it is communicating to a sink device, which determines local network links from nonlocal ones. An actual round trip time calculation is performed only by the source device and the sink device can be relatively passive. The duties of the sink device are performed in hardware and involve (trivially) modifying the received message while moving the message from the input isochronous channel buffer to the output isochronous channel buffer.

Abstract: An OCAP software download method improves the efficiency of software download in the OCAP for delivering operational software to consumer STBs. The download method allows many STBs to receive the software that is streamed from the cable headend over the cable plant to the STBs. Rather than servicing one STB per request, the download method utilizes a scheduled download method with synchronization and broadcasting protocol to allow many STBs to receive the data sent in one request.

Abstract: A Networked Digital Audio Amplifier (NDAA) uses a 1394 connection to connect devices to the NDAA in an digital A/V network of devices. The NDAA addresses the audio amplifier needs of the digital A/V network, whereby there is no need for a conventional AV Receiver, entirely. Further, the wiring is much simplified as a result. In addition, unnecessary connections and wiring that are commonly and conventionally used in audio consumer electronics equipment is eliminated.

Abstract: A method and system for pushing asynchronous notifications to devices in a network including client devices and server devices. A connection is established between a client device and a server device, wherein the client device sends a request for data to the server device, the server device includes a notification tag in a reply to the request from the client device for the client device to maintain the connection to the server device to await notifications from the server device, the client device receives the reply from the server device and checks for a notification tag in the reply such that if the reply includes a notification tag the client device maintains the connection to the server device to send notifications to the client device via the connection.

Abstract: The present invention provides a digital monitor that can be fully network connected, without including unnecessary components therein, similar to the way fully functional Digital Televisions (DTVs) are connected to a network.
