Caveo Technology's products are based on a standard formula:
Motion sensing technologies fall into two categories:
self-referenced and externally-referenced. Self-referenced, or inertial,
sensors sense their own motion, and, therefore, the motion of the
object to which they're attached. Externally-referenced sensors
sense the motion of one object relative to another.
Inertial sensors do not require an external reference. They use their own mass, or inertia, as a frame of reference. These types of sensors have been used for missile, rocket, and submarine guidance for years. They are also found in applications as varied as earthquake monitoring and detection, airbag deployment, and active-damping systems for snow skis and airplane wings.
Caveo's product solutions employ a range of self-referenced
motion sensors including micromachined accelerometers, low-power
gyroscopes, piezoelectric vibration sensors, and others.
The raw motion data collected by our sensors include meaningful information (signal) and extraneous or unwanted information (noise). We use a range of processing technologies and techniques to make sense of our motion observations and understand the associated events. These "motion algorithms" are the building blocks for smart motion-sensing systems.
Depending on the application, the processing hardware
used may include analog filters and discrete logic circuits, embedded
digital microcontrollers, and dedicated applications running on
a personal computer. One of our core competencies is designing the
software to use little code space so that the algorithms can be
managed with the smallest microcontroller. This is important, because
many of our applications will be mobile ones, where small size and
low power consumption are important.
Caveo's products are able to make decisions and take actions depending on their application. Here are some examples in current products:
Caveo Anti-Theft's software drivers are integrated with the operating system and initiate security responses, including audio warnings, denying access to protected files, and preventing startup of the operating system. They also provide a variety of convenient setup options for the user, such as arming when the screen saver comes on, changing the perimeter of protection and using the alarm sound.
The Caveo-enabled touch sensing system for artwork has an integrated
transmitter to enable direct communication with existing museum
security systems. We envision building wireless communications capabilities
into a wide range of future products. One wireless product, currently
under development, interfaces with existing WiFi 802.11 networks
in order to track the locations of people and objects.
