An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

A technique is provided for detecting episodes of cardiac ischemia based on an examination of the total energy of T-waves. Since cardiac ischemia is often a precursor to acute myocardial infarction (AMI) or ventricular fibrillation (VF), the technique thereby provides a method for predicting the possible onset of AMI or VF. Briefly, the technique integrates internal electrical cardiac signals occurring during T-waves and then compares the result against a running average. If the result exceeds the average by some predetermined amount, ischemia is thereby detected and a warning signal is provided to the patient. The maximum slope of the T-wave is also exploited. Techniques are also set forth herein for reliably detecting T-waves, which help prevent P-waves from being misinterpreted as T-waves on unipolar sensing channels. The T-wave detection technique may be used in conjunction with ischemia detection or for other purposes.

Disclosed are a receiver circuit, method and design architecture of a decision feedback equalizer (DFE) Clock-And-Data Recovery (CDR) architecture that utilizes/produces one sample-per-bit in the receiver and reduces bit-error-rate (BER). An integrating receiver is combined with a decision feedback equalizer along with the appropriate (CDR) loop phase detector to maintain a single sample per bit requirement. The incoming voltage is converted to a current and connected to a current summing node. Weighted currents determined by the values of previously detected bits and their respective feedback coefficients are also connected to this node. Additionally, the summed currents is integrated and converted to a voltage. A sampler is utilized to make a bit decision based on the resulting voltage. After sampling, the integrator is reset before analysis of the next bit. The necessary amplification is achieved by maximizing the sensitivity of the latch, using integration in front of the data latch.

In a semiconductor wafer marking apparatus having a marking interlock system and a semiconductor wafer marking method using the same, the semiconductor wafer marking apparatus includes a laser head unit including a flowcell having a laser radiation region on an upper surface thereof and a laser source radiating laser energy on the laser radiation region in response to an input current. An optical system focuses the laser energy radiated from the laser source to form a laser beam and radiates the laser beam on the semiconductor wafer. A cooling water reservoir stores cooling water. A pipe is disposed in the flowcell and connected to an inlet and an outlet of the cooling water reservoir. The cooling water flows through the pipe to maintain the laser radiation region of the flowcell at a constant temperature. A marking interlock system detects leakage of cooling water from the pipe, an abnormal temperature of the laser radiation region, and an abnormal input current supplied to the laser source, and generates a marking interlock signal to terminate a marking operation of the semiconductor wafer. A marking unit turns off the laser source to terminate the marking of the semiconductor wafer in response to the marking interlock signal generated by the marking interlock system.

Power supply rejection (PSR) peaking in Low Dropout (LDO) voltage regulators can lead to reduced bandwidth and efficiency. This paper presents a new design method by combining power transmission lines (PTL) with LDOs for enhancing its bandwidth and efficiency. This approach is applicable for LDOs regulating high speed I/O drivers. The PTL combined with decoupling capacitors on the package or board are used to mitigate the PSR peaking. This methodology is demonstrated using printed circuit board test vehicles with off-the-shelf components. When compared to conventional approaches, the PTL solution showed ˜80% lower power supply noise.
