The machines now under development in California and New Mexico represent a new type of hopping robot because they don't maintain continuous motion or balance.
Compared with Sojourner, which roamed within only a few meters of its lander, the new generation of hopping machines looks toward much broader horizons--in space or on Earth.
And because Frequency Hopping provides complete synchronization to other device signals, including modulation and digital events, users test devices as they function in the real world.
The Frequency Hopping option, provides users with even greater test advantages, including testing of Bluetooth(TM) wireless devices.
Microchip's patented KEELOQ code hopping technology creates a high degree of security using a long code word length together with encryption and automatic synchronization techniques.
The KEELOQ code hopping methodology circumvents code capturing since a different code is used with each successive transmission and a previous code is never accepted again.
The code hopping technology uses a complex non-linear cryptographic algorithm to encode the transmission sequence.
The key is used to generate a 32-bit hopping code to practically eliminate the possibility of unwanted access from code grabbing and scanning.
The HCS300/HCS301 contains a programmable 28-bit serial number to identify the transmitter and a 64-bit encryption key unique to each device that is used to generate a 32-bit hopping code to practically eliminate the possibility of unwanted access from code grabbing and scanning.
In November 1995, Microchip acquired the KEELOQ code hopping technology and patents and patent applications developed by Nanoteq of South Africa, along with the worldwide marketing rights.
Available for volume shipments April 1996, both devices use the KEELOQ code hopping algorithm which combines high security, a small package outline and an extremely low cost to make this an ideal solution for unidirectional remote-keyless-entry systems.
In November, 1995 Microchip acquired the KEELOQ code hopping technology and patents and patent applications developed by Nanoteq of South Africa, along with the worldwide marketing rights.
Prince understands the need for creating highly secure RF systems and selected the KEELOQ code hopping
technology because of its versatility, robustness and presence in this market," said Dr.
The Keeloq hopping
code technology is used for enhanced security in wireless/remote controlled systems using infrared, radio frequency or microwave transmissions, as well as highly secure smart card solutions.
