A Novel Way to Measure the Density of a Solid By David Chandler, Porterville College I was recently explaining to a middle school teacher how to measure the density of a solid object (that is denser than water) by comparing its weight in air and its weight suspended in water. The measured weight when suspended in water is the actual weight minus the buoyant force. Archimedes Principle equates the buoyant force to the weight of the water displaced.

  • revised method
  • mass of the ball by the volume of the ball
  • method to students
  • precision for the volume measurement
  • buoyant force

Product Development Kit14 Display System Solution 15LCD CONTROLLER
Solomon Systech’s SSD1960 /61/62/63 Display Controllers are ideal for mobile and handheld
applications that require high-resolution display. These controllers contain an embedded
SRAM which serves as a frame buffer between the host processor and the LCD panel.
The chips support 8/9/16/18-bit indirect CPU interface and 18/24-bit RGB LCD interface.
The feature set includes hardware display rotation (0°, 90°, 180° and 270°), mirroring and
windowing, and display enhancement such as brightness, contrast and saturation control.
Power consumption is one of the most pressing challenges in designing consumer
electronics, especially for battery-operated devices such as mobile phones, personal
navigation devices and portable media players. As the LCD display increases in size and
resolution, the backlight becomes the most power consuming part in the system. The
SSD1960/61/62/63 controllers feature the Solomon Systech’s Dynamic Backlight Control
(DBC) technology which adds value to portable device manufacturers without sacrificing
the display quality of the end products.
Applications: Mobile phone, health care product, industrial equipment, home appliance,
digital photo frame, POS terminal, etc.
