Organic electroluminescence element and an exposure unit and image-forming apparatus both using the element

Abstract: The invention has an object of providing an organic electroluminescence element with a large emitted light quantity, an exposure unit and an image-forming apparatus both using the element. The organic electroluminescence element in accordance with the invention has, on a substrate, an anode acting as a hole injection electrode, a cathode acting as an electron injection electrode, a plurality of light emission layers each having a light emission region and a charge generation layer injecting electrons into the light emission layer lying close to the anode and injecting holes into the light emission layer lying close to the cathode, these layers being arranged between the anode and the cathode, and is configured so that the work function of the charge generation layer is set higher than the ionization potential of the light emission layer lying close to the anode.

A Wearable 8-Channel Active-Electrode EEG/ETI Acquisition System for Body Area Networks

Abstract: This paper describes an 8-channel gel-free EEG/electrode-tissue impedance (ETI) acquisition system, consisting of nine active electrodes (AEs) and one back-end (BE) analog signal processor. The AEs amplify the weak EEG signals, while their low output impedance suppresses cable-motion artifacts and 50/60 Hz mains interference. A common-mode feed-forward (CMFF) scheme boosts the CMRR of the AE pairs by 25 dB. The BE post-processes and digitizes the analog outputs of the AEs, it also can configure them via a single-wire pulse width modulation (PWM) protocol. Together, the AEs and BE are capable of recording 8-channel EEG and ETI signals. With EEG recording enabled, ETIs of up to 60 kΩ can be measured, which increases to 550 kΩ when EEG recording is disabled. Each EEG channel has a 1.2 GΩ input impedance (at 20 Hz), 1.75 μVrms (0.5-100 Hz) input-referred noise, 84 dB CMRR and ±250 mV electrode offset rejection capability. The EEG acquisition system was implemented in a standard 0.18 μm CMOS process, and dissipates less than 700 μW from a 1.8 V supply.
