  • Patent number: 10568008
    Abstract: The invention relates to a terminal (10) for a cellular communications network (1000). The terminal is configured to maintain a first set (S1) of at least n radio cells, wherein n is equal to or greater than three, wherein a quality measure (q) value of each of the n radio cells, which depends on a received signal power associated with reference signals transmitted in said cells and received by said terminal (10), exceeds a threshold. The terminal further determines whether a quality measure value of a further radio cell, which is not comprised in the first set, exceeds the quality measure value of the radio cell comprised in the first set with the m-th best quality measure value, m ranging from 1 to n?1, by a predetermined amount. If the quality measure value of the further radio cell (c12) exceeds the quality measure value of the m-th best radio cell, modification of the first set is arranged, whereby a second set (S2) is obtained. The second set comprises the further radio cell.

  • Publication number: 20170049410
    Abstract: A method of capturing an x-ray image including providing an intraoral sensor having an array of pixels having a plurality of pixel clusters and a plurality of lines of pixels, each line of pixels having a first number of pixels different from the pixel clusters. The method may also include directing x-ray radiation toward the intraoral sensor and generating an electrical signal correlated to the x-ray radiation that impinges the pixel. The method may also include processing electrical signals generated by one or more pixels in the plurality of pixel clusters, generating at least one combined signal for at least one of the pixel clusters based on the signals from each of the pixels in the at least one of the pixel clusters, and initiating the capture of the image generated with information from each of the pixels in the array of pixels that is exposed to radiation.

  • Patent number: 9492129
    Abstract: Automatic triggering of an intraoral x-ray sensor used in a dental x-ray imaging system. The intraoral sensor has an array of pixels. The array of pixels has a plurality of lines of pixels, and each of the pixels generates an electrical signal correlated to x-ray radiation that impinges that pixel. An electronic control unit is connected to the intraoral sensor to receive electric signals from the array of pixels. The electronic control unit destructively reads pixel clusters in one or more of the plurality of lines of pixels. The electronic control unit is configured to generate a dose-correlated signal based on the signals from each of the pixel clusters in each of the one or more lines of pixels and initiate capture of an image generated with information from each of the pixels in the array of pixels, when the combined signal exceeds a predetermined threshold.

  • Patent number: 9259197
    Abstract: An intraoral x-ray sensor with embedded standard computer interface. The sensor includes a data transfer cable. In one embodiment, the cable is quad-twisted USB cable and includes two data lines, a ground line, and fillers twisted within a metallic sheath. The cable is symmetrically organized about a centerline. The symmetric cable has an improved life due to the ability to withstand mechanical stress (e.g., rotational stress). The sensor includes a processor and a housing with an inner metallization layer. The sheath is coupled to the inner metallization layer to transfer heat generated by the processor from the inner metallization layer to the sheath.

  • Patent number: 8324587
    Abstract: A system and method for automatic detection of x-rays at an x-ray sensor. A source emits x-ray radiation towards an x-ray sensor, and the x-ray sensor automatically detects the x-ray radiation. The x-ray sensor automatically detects x-ray radiation by evaluating a time series and determining that a voltage threshold is crossed a certain amount of time earlier than the average time it takes the voltage threshold to be crossed from dark current and other noise.
