  • Patent number: 7983440
    Abstract: A system and method are provided for selecting frames of a compressed video stream that may be used for client-side watermarking. In general, a content source evaluates a number of Intra-Frames (I-Frames) in the compressed video stream using a sample watermark that is similar to actual watermarks that may be used for client-side watermarking. More specifically, each of a number of I-Frames in the compressed video stream is evaluated by first watermarking the I-Frame with the sample watermark. Associated frames in the compressed video stream are then decoded using the watermarked I-Frame. An error value for the decoded video frames is then computed. If the error value is outside of a predetermined error threshold range, the I-Frame is selected as an I-Frame that may be used for client-side watermarking.

  • Patent number: 7981146
    Abstract: A method of treating meibomian gland dysfunction. Heat is applied to the inside of the eyelid to provide conductive heat transfer to the meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. Temperatures at the meibomian glands reach desired levels more quickly and efficiently when heating the inside of the eyelid. Reaching such higher temperature levels may be instrumental in removing obstructions in the meibomian glands. Less time may also be required to reach desired temperature levels when applying heat to the inside of the eyelid. A force may also be applied to the outside of the patient's eyelid to improve conductive heat transfer and reduce blood flow in the eyelid that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions.

  • Patent number: 7983200
    Abstract: The performance of a voice conference using a packet-based conference bridge can be improved with a number of modifications. In one modification, the conference bridge receives speech indication signals from the individual packet-based terminals within the voice conference, these speech indication signals then being used by the conference bridge to select the talkers within the voice conference. This removes the need for speech detection techniques within the conference bridge, hence decreasing the required processing power and the latency within the conference bridge. In another modification, the conference bridge sends addressing control signals to the individual packet-based terminals selected as talkers, these addressing control signals directing the terminals selected as talkers to directly transmit their voice data packets to the other terminals within the voice conference. This direct transmission of voice data packets can reduce transcoding and latency within the network.

  • Patent number: 7981145
    Abstract: In one embodiment consistent with the present invention a method of treating mammalian meibomian glands involves clearing the glands by applying a regulated heat to an eyelid containing the meibomian glands to a temperature adequate to melt obstructions in the meibomian glands to put the obstructions in a fluid or suspension (melted) state and maintaining the heat for a time period adequate to melt the obstructions. The glands can then be mechanically treated to express fluid from the glands, wherein the treating is carried out either during the time period or after the time period but while the obstruction remains in a fluid state. Subsequent pharmacological treatment of the glands by use a pharmacological agent (topical or systemic) can then be used to assist in maintaining proper flow of lipids from the glands. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Patent number: 7961696
    Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-1 and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

  • Patent number: 7957512
    Abstract: The present invention provides an audio source selection process for a conference bridge. The conference bridge receives multiple audio sources and selects at least one of the audio sources based on the relative signal levels associated with the audio signal at each of the audio sources. The audio signals associated with the selected source are delivered to conference participants via one or more audio outputs. The conference bridge will repeatedly employ a selection process to select an audio source based on signal level measurements for the audio signals of the audio sources. During the selection process, the influence of a selected audio source relative to the other unselected audio sources is reduced, after the selected audio source has remained selected for more than a first time period.

  • Patent number: 7944817
    Abstract: The present invention establishes reserved paths between nodes in a central packet network and in local networks attached to the central network. Each reserved path has a defined bandwidth and may be implemented as an LSP in an MPLS network or as a PVC in an ATM network. Associated with each reserved path is a virtual trunk group representing the same bandwidth as the virtual path. Telephony calls requiring media flows associated with a channel in the virtual trunk group will transport packets along the reserved path associated with the virtual trunk group. Access to the reserved path is limited to telephony media flows associated with a virtual trunk group to ensure adequate bandwidth at all times for the number of channels associated with the virtual trunk group. Backup reserved paths may be associated with the primary reserved path to provide the necessary redundancy required for voice-based telephony applications.

  • Patent number: 7941764
    Abstract: A system and method for assigning user preference settings for fields in a category using selected settings for only a subset of the media category fields is disclosed. A subset of fields for a media category is defined. A base setting for each field in the subset of the category fields is established. The base setting may be a weight or preference value. The base setting may be established by the user selecting a base setting or may be a default base setting. Once a user selects the settings for the subset of category fields, a set weight for the fields in the category not in the subset is determined using the base setting. That is possible because the fields in the subset of category fields are chosen from fields that contain aspects and attributes of the other fields.

  • Patent number: RE42497
    Abstract: An apparatus and method for obtaining depth-resolved spectra for the purpose of determining the size of scatterers by measuring their elastic scattering properties. Depth resolution is achieved by using a white light source in a Michelson interferometer and dispersing a mixed signal and reference fields. The measured spectrum is Fourier transformed to obtain an axial spatial cross-correlation between the signal and reference fields with near 1 ?m depth-resolution. The spectral dependence of scattering by the sample is determined by windowing the spectrum to measure the scattering amplitude as a function of wavenumber.
