An electric skateboard is disclosed. In one aspect, the electric skateboard comprises a foot placement section. The electric skateboard comprises a wheel suspension truck connected to the foot placement section. The electric skateboard comprises a first wheel and a second wheel, wherein the first wheel and the second wheel are spaced apart and substantially parallel to one another and wherein the first wheel and the second wheel are connected to the wheel suspension truck. The electric skateboard comprises a deformation sensor module attached to the wheel suspension truck, the deformation sensor module configured to generate a weight signal and a gravity angle signal associated with the electric skateboard. The electric skateboard comprises a control logic configured to output control signals that control a movement of the electric skateboard in response to the weight signals, and the gravity angle signals.

A sensor interface includes on-chip relaxation oscillator circuit and a PLL that operate cooperatively to generate a highly accurate clock signal on-chip using low-power components. A photodiode generates a current signal based on an optical signal that is representative of a sensor signal. An ADC that operates based on the highly accurate clock signal generates a digital signal based on the current signal generated by the photodiode, and a processor processed the digital signal to estimate sensor data within the sensor signal. Examples of characteristics that may be sensed can include environmental characteristics (e.g., temperature, humidity, barometric pressure, etc.) and/or biomedical characteristics (e.g., body temperature, heart rate, respiratory rate, blood pressure, etc.). If desired, an amplifier processes the photodiode-provided current signal before it is provided to the ADC. Also, one or more CDACs that generate feedback currents may be used to reduce noise sensitivity of the sensor interface.

Systems, apparatuses, and methods provided for ping-pong charge pumps. Flying capacitors present in ping-pong charge pumps are operated out of phase to increase equalization periods. Out-of-phase operation also decreases voltage differences between flying capacitors during equalization periods thus decreasing ping-pong charge pump output voltage ripple and snapback. The voltages of the flying capacitors may be equalized without the use of an equalization switch. Differential control currents that are based on the voltage difference between the flying capacitors are used to enable or disable the flying capacitors from driving an output load of the ping-pong charge pump during certain phases of operation. A capacitor with a lower voltage may be disabled, thus providing for voltage equalization as the enabled capacitor sources current to the output load. The flying capacitors are also equalized during overlapping time periods in which the flying capacitors are charging.

A circuit for a charge-pump low-dropout (LDO) regulator may include a comparator circuit configured to control a pass transistor based on an error signal. A pre-charge path may be provided between a supply voltage and an output node of the regulator. The pre-charge path may be configured to allow charging of an output capacitor to a pre-charge voltage during a pre-charge operation mode. The output capacitor may be coupled between the output node of the regulator and ground potential. The pass transistor may be configured to allow charging of the output capacitor during an LDO mode of operation. A charge-pump circuit may be configured to provide a current for charging the output capacitor during the LDO mode of operation.

A multi-mode line driver circuit designed to be fabricated in a CMOS process and capable of supporting a plurality of operating modes corresponding, for example, to different profiles of communication standards such as xDSL standards. The line driver circuit incorporates integrated mode switches with a two-stage amplifier architecture to relax amplifier requirements by distributing the signal gain into two amplifier stages. Reconfigurable feedback loops are provided to permit design optimization for particular modes of operation (e.g., ADSL and VDSL compliant modes). In one embodiment implemented as a Class-H amplifier, lift amplifier(s) are provided between a first amplifier stage and a second amplifier stage for controlling voltage supply levels of the second amplifier stage. The lift amplifiers may be enabled by voltage threshold detection circuitry that monitors either the input or the output signals of the first amplifier stage depending on the operable transmission mode.

A mouse growth hormone secretagogue receptor has been isolated, cloned and sequenced. This receptor is characteristic of the G-protein family of receptors. Mouse growth hormone secretagogue receptors may be used to screen and identify compoumds which bind to the mouse growth hormone secretagogue receptor. Such compounds may be used in the treatment of conditions which occur when there is a shortage of growth hormone, such as observed in growth hormone deficient children, elderly patients with musculoskeletal impairment and those recovering from hip fracture and osteoporosis. Targeted disruption of the mouse GHS-R gene may prove useful in elucidation of the mechanism of action and role of the growth hormone secretagogues in human and animal physiology.

Transgenic non-human mammals which express in their brains a nucleic acid construct comprising a DNA sequence encoding a human amyloid precursor protein FAD variant where at amino acid position 717 valine is substituted by isoleucine. These transgenic non-human mammals can be assays systems for determining compounds which are effective in modulating production of human amyloid precursor protein in brain and in isolated neuronal cells. Specifically exemplified are transgenic mice whose genome comprises a DNA sequence encoding a human amyloid precursor protein FAD variant where at amino acid position 717 valine is substituted by isoleucine operably linked to a Thy-1 promoter. The mice are shown to produce the APP-FAD variant in their brains by mRNA and protein assays.
