  • Patent number: 6734667
    Abstract: A liquid level sensor is provided for use with a container. The sensor protrudes through an opening in the container. The sensor includes a float linked by means of a linkage to a first magnet axially rotatable on a first axis. The first magnet has a magnetic moment with a nonzero component at a right angle to the axis. A divider separates the first magnet from a second magnet having a magnetization and axially rotatable on a second axis. The second magnet has a nonzero magnetic moment at a right angle to the second axis. The first and second magnets are juxtaposed in magnetic linkage so that the second magnet is urged to follow the first magnet in rotation. The divider plugs the opening in the container. A magnetic field sensor is positioned to sense axial magnetic field strength at a location offset from the second axis.

  • Patent number: 6735234
    Abstract: A passively mode-locked optically pumped semiconductor vertical-external-cavity surface-emitting laser (OPS-EXSEL) is disclosed. The laser is mode locked by a semiconductor saturable absorber mirror (SESAM) which forms part of an external cavity. Both the beam-quality limitations of edge-emitting lasers, and the power restrictions of electrically pumped surface-emitting lasers are overcome. The laser uses a semiconductor wafer in which a stack of quantum wells is grown adjacent to a single Bragg-mirror structure. Light from one or more multi-mode high-power diode lasers is focused onto the face of the wafer and pumps the wells by absorption in the barrier regions. The area of the laser mode on the active mirror can be about 104 times larger than the mode area on the facet of an edge-emitting laser, offering scope for the generation of high average power and large pulse energy. At the same time the external cavity enforces fundamental mode operation in a circular, near-diffraction-limited beam.

  • Patent number: 6725127
    Abstract: A package storage and delivery system includes electronically controlled lockers disposed at or near customer locations. Each locker is unlocked by a courier, preferably by means of a short-range transceiver or transmitter carried on the courier's person. The customer can unlock the locker and receive the delivered package. Cryptographically signed communications are employed along with nonvolatile usage logs to minimize the risk of loss of a package or fraud by courier or customer. The lockers may be stackable, permitting a delivery courier to add lockers in the event a customer receives too many deliveries to fit into a single locker. Each box has, of course, a physical location, and has associated with it an address code indicative of the physical location, for example by means of a human-readable or compressed representation of the precise latitude and longitude. A package delivered to such a box preferably bears the address code.

  • Patent number: 6702100
    Abstract: Flat articles are taken over from a supply device supplying the products e.g. in the form of an imbricated stream and, for creating groups, are transferred to a conveying-away device. Thereby the supply direction and the conveying-away direction are angled in the horizontal plan view. For the transfer of the articles devices are used having a circulating conveying organ with laterally protruding gripper arms and grippers arranged on the gripper arms. The circulation track of the conveying organ extends in a take-over direction through a take-over zone and in a transfer direction through a transfer zone and represents a deflection between take-over and transfer zone.

  • Patent number: 6699693
    Abstract: A method is provided for replicating DNA, and in particular for replicating large segments of DNA. A primer is combined with a target DNA molecule to be replicated. The primer is designed to be at least partially homologous to a known site on the target DNA, and to create a D-loop when hybridized with that site. A replisome is then assembled at the D-loop, and this replisome creates a copy of the DNA, starting at the primer binding site. By utilizing two species of D-loop primers which bind to remote sites on the DNA flanking a region to be replicated, large sections of DNA can be replicated in a manner comparable to PCR. The replicated DNA can be analyzed to detect variations in the genetic sequence of the target, for linkage mapping and as a source of longer DNA molecules having a desired sequence.

  • Patent number: 6695468
    Abstract: Several watches (1.1-1.4) are placed in an arrangement and interconnected by connecting means (2.1-2.3). The watches (1.1-1.4) have cover glasses (11.1-11.4), dials (12.1-12.4), cases (13.1-13.4), winders (14.1-14.4) and time indicating means (15.1-15.4). The connecting means (2.1-2.3) are e.g. located on a carrier element (20) containing the dials (12.1-12.4) of all the watches (1.1-1.4). The carrier element (20) has preset breaking lines (3.1-3.3) in the form of perforations and cross-sectional reductions between the watches (1.1-1.4), so that said watches (1.1-1.4) can be separated from one another. The arrangement or watches (1.1-1.4) separated therefrom can be used as fashion accessories jewellery, pendants, etc. There are no practical limits to the design of the arrangement and its watches (1.1-1.4). The arrangement can be manufactured in a simple, advantageous manner, so that it is in particular possible to take account of rapidly changing fashions.

  • Patent number: 6678242
    Abstract: A pair of devices (400, 401) appear to be a Common Channel Signaling (CCS) network nodes on each end of a point-to-point digital data link, that is, a normal CCS signaling link (402, 403). Multiple transport methods may be used to provide a redundant and diverse path for the signaling link. These methods include the encapsulation of the CCS protocol, at one or more layers, within other network protocols. In another embodiment, the present invention implements a virtual Signal Transfer Point by means of one or more encapsulating STPs (eSTPs). A packet data network (408) using standard packet-switched data protocols, rather than a backplane bus or special-purpose network, connects the encapsulating STPs (405, 406), and CCS messages are dynamically routed across the internal packet data nework to an appropriate eSTP for transmission to the appropriate next hop address.
