  • Patent number: 11991572
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Publication number: 20240145119
    Abstract: A transparent conductive film comprises a substrate, a metal nanowire layer disposed on the substrate, and a water blocking protective layer, which has water absorbing particles and is disposed on the metal nanowire layer. The transparent conductive film has a first absorption peak in a 2750 cm?1 to 3000 cm?1 wavenumber region and a second absorption peak in a 3000 cm?1 to 3750 cm?1 wavenumber region using FTIR detection. A ratio of a maximum peak intensity of the second absorption peak to a maximum peak intensity of the first absorption peak ranges from 0.18 to 0.50, and a haze value of the transparent conductive film is 1.7% or less. The transparent conductive film can overcome the problems of poor bending resistance and visibility and can be appropriately applied to touch sensors due to bendability and high water blocking performance of the transparent conductive film.

  • Publication number: 20240142684
    Abstract: An electronic device such as a wristwatch may be provided with conductive structures. The conductive structures may include a sensor electrode for an electrocardiogram (ECG) sensor. A coating may be disposed on the sensor electrode to reflect particular wavelengths of visible light so that the sensor electrode exhibits a desired color. The coating may include adhesion and transition layers on the sensor electrode, an opaque coloring layer on the adhesion and transition layers, and a thin-film interference filter on the opaque coloring layer. The thin-film interference filter may have an uppermost diamond-like carbon (DLC) layer. The DLC layer may contribute to the color response of the coating while concurrently minimizing noise in ECG waveforms gathered by the ECG sensor using the sensor electrode.

  • Patent number: 11258599
    Abstract: A system and method use a physical unclonable function in a PUF circuit on an integrated circuit to generate a security key, and stabilize the security key by storage in a set of nonvolatile memory cells. The stabilized security key is moved from the set of nonvolatile memory cells to a cache memory, and utilized as stored in the cache memory in a security protocol. Also, data transfer from the PUF circuit to the set of nonvolatile memory cells can be disabled after using the PUF circuit to produce the security key, at a safe time, such as after the security key has been moved from the set of nonvolatile memory cells to the cache memory.

  • Patent number: 8194457
    Abstract: A soft program method is provided for recovering memory cells of a memory array. In an embodiment, the method includes the following steps. Memory blocks of the memory array are soft programmed with first bias voltage. A selected memory unit within a selected memory block is then soft programmed with second bias voltage. Next, whether a judging criterion is met is determined. If not, the method is repeated from the step of soft programming with the second bias voltage; if so, whether the selected unit is a last memory unit is determined. If the selected unit is not the last memory unit, other memory unit is assigned as the selected memory unit and the method is repeated from the step of soft programming with the second bias voltage. When the selected unit is the last memory unit, the memory array is bit-by-bit soft programmed with a third bias voltage.

  • Publication number: 20110157584
    Abstract: The present invention is directed to a method of calibrating a light source. In one embodiment, a standard image sensor is used to capture emitted light of a standard and a to-be-calibrated light source in order to obtain a standard and a nonstandard image, respectively. A standard and a nonstandard luminance response are generated according to the standard and the nonstandard image, respectively. The to-be-calibrated light source is adjusted until the nonstandard luminance response is about equal to the standard luminance response. In another embodiment, the standard image sensor is used to capture emitted light of the standard and the to-be-calibrated light source. According to sampled outputs of the standard image sensor, a standard and a nonstandard chrominance response are respectively generated, which are used to compensate an image sensor under test.

  • Patent number: 7909969
    Abstract: A gas diffusion layer with a micro protective layer is utilized in the electrochemical cells. The cell mainly includes end plates, current collectors, flow field plates, gas diffusion layers, catalyst layers, a proton exchange membrane and a circuit unit. When the cell functions as a fuel cell, hydrogen reacts with oxygen to generate electricity and water. Reversely, when the cell functions as a water electrolysis cell, water was decomposed electrolytically to produce hydrogen and oxygen gases. In this manner, the present invention particularly has the gas diffusion layer to be coated with a micro protective layer so as to prevent the gas diffusion layer from being corroded by active oxygen species generated within the oxygen electrode under the catalysis during water electrolysis operation.
