Pulse Technique TRIZ Cases
- Variable-Resistor Power Supply for Fast Start-Up Voltage Stability
A timed resistance increase speeds power-supply start-up while keeping output voltage stable under varying or negative input voltage.
- MOS Current Pulse Circuit Without Inductors for Laser Sources
MOS transistors and op-amp feedback replace inductive DC/DC conversion to deliver compact, higher-frequency current pulses for laser sources.
- SPAD TDI Image Sensor with Digital Stage Transfer for Low-Noise Imaging
SPAD-based digital counting replaces analog TDI accumulation to cut readout noise and preserve high imaging quality at lower cost.
- Shared-Path Frequency Divider for Clock Delay Matching
A shared-path clock divider keeps common and reduced frequency outputs at nearly the same delay, avoiding extra matching circuitry and power.
- Stylus End Cap Pressure Detection With Dual-Threshold Switching
A movable stylus end cap uses electrical coupling and switch actuation to detect two pressure thresholds for distinct input commands.
- Stylus End-Cap Pressure Sensing via Dual-Action Switch Coupling
A movable end cap uses capacitive coupling and switch actuation to add two stylus pressure commands without extra circuitry.
- Touch Sensor Layer Structure for Selective ITO Etching
An intermediate conductive layer prevents ITO re-crystallization, enabling selective etching and avoiding short or open circuits in touch sensors.
- Semiconductor Counting Circuit With Overcount Prevention Control
A counting over signal stops further input at a set maximum code, preventing overcounting and improving semiconductor counting accuracy.
- Touch Interface Feedback for Press Duration Input Signals
Visual, acoustic, or haptic feedback shows press duration thresholds, helping users trigger the right touch input quickly with less distraction.
- Counter Synchronization Using Independent Clocks Without Count Jumps
Independent oscillators synchronize by matching periodic flags and resetting counters together, avoiding discontinuous timer values.
