  • Patent number: 5809590
    Abstract: A waterproof urinal mat which contains humorous or informational messages printed or coated over with thermochromic inks. The mat is formed to fit in a urinal, such that included text and artwork printed onto the mat with temperature sensitive, thermochromic inks display multiple images at an ambient temperature and upon being contacted with urine or flush water. In alternative arrangements, thermochromic inks of selected activation temperatures are variously printed onto the substrate in relation to an opaque image before coating the substrate with a waterproof covering or laminate. Two or more images are thereby visible upon contacting the mat with urine and flush water. Apertures and protrusions at the mat prevent splashing and direct liquid flow relative to the images.

  • Patent number: 5808241
    Abstract: A thin film transmission line, delay line constructed on a ceramic substrate. A serpentine, transmission line conductor and a surrounding, coplanar border ground are plated in registry onto the substrate. Discrete ground paths which project from the border are interspersed between the conductor windings to electrically shield adjacent windings. A hard coat epoxy resin covers the signal layer, which may support a sputtered ground plane that is connected to the border ground. An alternative delay line provides overlying ground fingers within the dielectric covering layer which are aligned to the channel spaces between the conductor windings. Both assemblies provide an increased number of conductor lines per chip. Edge coupled terminations are provided at the substrate to accommodate multi-layer assemblies of the delay line and/or circuit terminations.

  • Patent number: 5736927
    Abstract: A security alarm system including multiple, zone distributed audio monitors and alarm sensors which report and verify detected alarms and communicate with a system controller and central station. Ambient audio is continuously and selectively recorded in a storage memory and is replayable to verify alarms detected at the alarm sensors. During pre-alarm conditions, all audio inputs are summed and recorded. During an alarm state, the audio input of the audio monitor physically closest to a reporting alarm sensor is automatically selected and the post-alarm audio activity is recorded only for that sensor. The central station is able to selectively communicate via a phone link with each audio controller and engage in half duplexed voice communication with the alarm site, remotely playback and listen to the locally recorded audio data, or program each audio controller. The monitored audio data is stored in RAM storage in discreet segments corresponding to predetermined periods of pre-alarm and post-alarm data.
