  • Patent number: 9869018
    Abstract: A method of solid precursor delivery for a vapor deposition process is provided. In some embodiments, a precursor ampoule is provided including a solid precursor arranged in the precursor ampoule. A solvent is added to the precursor ampoule including one or more ionic liquids to dissolve chemical species of the solid precursor and to form a liquid precursor. A carrier gas is applied into the liquid precursor through an inlet of the precursor ampoule. A gas precursor is generated at an upper region of the precursor ampoule by vaporization of the liquid precursor. The chemical species of the solid precursor are delivered into a vapor deposition chamber by the carrier gas. The chemical species of the solid precursor is deposited onto a substrate within the vapor deposition chamber.

  • Publication number: 20170269872
    Abstract: A hard disk monitoring method and a hard disk monitoring system are provided. The hard disk monitoring method includes: determining whether a speaker outputs a sound source by using a host system; if the speaker outputs the sound source, determining whether a performance of the hard disk is lower than a threshold by using the host system; if the performance of the hard disk is lower than the threshold, adjusting the sound source signal of the sound source by using the host system. Therefore, the hard disk monitoring method and the hard disk monitoring system inspect the performance of the hard disk when the speaker outputs the sound source. If the performance of the hard disk drops, the volume outputted by the speaker is dynamically turned down to stop the performance drop of the hard disk caused by the vibration generated by the speaker outputting the sound source.

  • Patent number: 8066510
    Abstract: A dental agent applicator has a barrel, a sealing plug, a delivery head and a plunger. The barrel has a proximal end, a distal end and a chamber defined through the barrel. The sealing plug is mounted in the chamber and hermetically obstructs the chamber. The delivery head is movably mounted on the distal end of the barrel and has a hub and a nozzle tip. The hub is mounted movably in the distal end and selectively moves the sealing plug to make the chamber communicate with the delivery head. The nozzle tip is mounted on the hub. The plunger is mounted slidably in the proximal end of the barrel. The delivery head is mounted permanently on the barrel. Using the dental agent applicator without having to replace any sealing cap with the delivery head is simple and convenient.

  • Patent number: 7988450
    Abstract: A dental impression tray has a base and a relator. The base has a biting portion and a handle. The biting portion is curved. The handle is formed on the biting portion and has an arc hole that is defined through the handle to receive impression material. The relator has a vertical bar and a horizontal bar. The relator is mounted in the arc hole and is fastened in the arc hole by impression material. The horizontal bar connects perpendicularly to the vertical bar. Therefore, the impression of the teeth to be crowned or veneered as well as the relation between the impression and the patient's face are obtained simultaneously.

  • Patent number: 7606154
    Abstract: A network device utilizes fair bandwidth allocation techniques based on configurable service classes. The network device comprises a scheduler that receives a packet associated with a service flow for delivery to a destination. The scheduler identifies a service credit associated with the service flow that represents a bandwidth allocation available for consumption by an associated service flow. Based on the identified service credit, the downstream scheduler assigns the packet to one of a plurality of hold queues. The number of hold queues may remain static during the allocation of bandwidth, which reduces the complexity of the scheduler and permits fair bandwidth allocation to occur. Such a queuing architecture also allows the downstream scheduler to achieve rate limiting and minimum bandwidth guarantee without using separate algorithms and/or architectures.

  • Patent number: 7277394
    Abstract: A wireless network (100) and method (200) for assigning a set of channels to a set of wireless devices (102-126) in the network where there are less channels than devices such that wireless devices are grouped in channel groups such that the wireless devices assigned to each channel group are positioned so as not to interfere with each other. In assigning an nth wireless device to a kth channel group, the nth and preferably one member of the kth channel group at a time are instructed to transmit simultaneously in order to ascertain if the nth wireless device interferes with or is interfered with by any member of the kth channel group.

  • Patent number: 7187669
    Abstract: The invention is directed to techniques for improving upstream communication in a DOCSIS-based cable network or other reservation-based TDMA system. In one example, the techniques may involve dynamically adjusting the size of a contention region in a MAP interval in which upstream time slot allocation is conveyed by a MAP message broadcasted by a cable modem transmission system (CMTS) to cable modems (CMs) sharing a common upstream DOCSIS channel. By adjusting the size of the contention region in the MAP intervals based on measured traffic parameters, the system can be dynamically responsive to different upstream traffic scenarios and thereby exploit maximal upstream data throughput continually.

  • Patent number: 6982960
    Abstract: A network protocol for low-cost, low-power devices coupled to a self-organizing wireless network using a spanning tree backbone architecture is described. In this protocol, physical and logical network construction and maintenance operations, which supports efficient data routing in the network, are performed. The construction phase in conjunction with the maintenance phase insures the self-organizing capability of the network. At the same time, the maintenance operations provide a self-healing mechanism so that the network can recover from node failures and a self-updating mechanism so that the network can expand as more nodes enter the system. Also, the logical backbone hierarchy will facilitate multi-hop communication. The construction of a logical layered spanning tree backbone architecture from an underlying physical topology allows seamless data communication routing between all nodes in the network.
