Abstract: A driving belt inspection device and method for a wafer transfer module is disclosed. The driving belt inspection device for a wafer transfer module includes: a data receiving unit for receiving current data of a motor connected to a driving belt; a calculation unit for calculating the rate of change of instantaneous current of the motor according to the received current data and acquiring a calculated value for inspection according to the calculated rate of change of instantaneous current of the motor; and a result determination unit for determining, if the calculated value is lower than a first reference value, that the driving belt is in a normal operation state, and determining, if the calculated value is higher than a second reference value, that the driving belt is in an abnormal operation state.

Abstract: A copolymer including a structural unit represented by Chemical Formula 1 wherein the copolymer is capable of improving luminous efficiency and durability, particularly, an improvement in luminescence life-span, of an electroluminescence device, particularly a quantum dot electroluminescence device.

Abstract: A recharging and medication storage hub for a re-usable drug-delivery device is provided. According to some embodiments, the hub comprises a housing defining a port sized to receive at least part of the re-usable drug-delivery device, a charging station disposed on the housing configured to charge a rechargeable power source mounted on the drug-delivery device, and a medication storage chamber disposed in alignment with the port, the storage chamber configured to store a single-use medication cartridge. When at least part of the drug-delivery device is inserted through the port and into the medication storage chamber, a coupling mechanism is configured to releasably couple with and withdraw the medication cartridge from the medication storage chamber. In some embodiments, the hub may further comprise a temperature-changing device configured to control an interior temperature of the medication storage chamber.

Abstract: Various embodiments provide for an improved ear-worn device for attaching the ear-worn device to an ear of a user using a hooking body. The hooking body may be secured to the user's ear. In some embodiments, a device body may be coupled to the hooking body via a hinge. The device body may be moved (relative to the hooking body) using the hinge to cause the ear-worn device to transition from a closed configuration to an open configuration, and vice versa.

Abstract: Provided is a failure prediction method using a failure prediction apparatus, including: receiving time-series data about measured performance parameters from a device under test; encoding the time-series data with a plurality of symbols corresponding to a predetermined range; calculating a transition probabilities between the symbols of the encoded time-series data, and generating a transition matrix according to the transition probabilities; calculating an abnormal indicator, which is a difference between the transition matrix and a pre-stored database, and an increased value of the abnormal indicator; and comparing the increased value of the abnormal indicator and a predetermined threshold value, and if the increased value of the abnormal indicator is greater than the predetermined threshold value, predicting that failure of the device under test is to occur.

Abstract: Various embodiments provide for an improved attachment apparatus for attaching the attachment apparatus to an ear of a user using a hook body. The hooking body may be secured to the user's ear, such as in response to receiving a deforming force from the user that causes the hooking body to deform in conformity with at least a portion of the root of the user's ear. In some embodiments, the hooking body may be coupled to the attachment body via the bridging member of the attachment body. Accordingly, the hooking body may be configured to secured the attachment apparatus to the user's ear. In some embodiments, a sealing body may be coupled to the plate member of the attachment body, and the cover body may form at least a partial acoustic seal around the user's ear while the hooking body is secured to the attachment apparatus to the ear.

Abstract: Various embodiments provide for an improved attachment apparatus for attaching the attachment apparatus to an ear of a user. In some embodiments, the attachment apparatus may include an attachment body that defines an opening configured to enable at least a portion of a user's ear to pass through the opening when the attachment apparatus is coupled to the user. In such embodiments, the attachment body may prevent an anterior portion of the ear from passing through the opening and may receive, from an interaction with the anterior portion of the ear, a force that biases the first attachment portion in a direction away from a median plane of the user. In some embodiments, the attachment body may secure the attachment apparatus to the ear of the user while the first attachment portion is biased away from the median plane of the user.
