A method and device for responding to an incoming call. A first device detects an incoming call from a caller. In response to detecting the incoming call, an indication of the incoming call is sent to a second device different from the first device. The indication identifies the caller. A message indicating a response to the caller is received from the second device.

Responding to incoming calls

A valve lifter guide () includes at least one conduit (). The conduit () has a first inwardly-curved surface () opposed to a second inwardly-curved surface () such that the conduit is capable of holding a valve lifter () between the first inwardly-curved surface () and the second inwardly-curved surface (). The valve lifter guide () may optionally include inwardly-curved alignment surfaces

Valve lifter guide

A signal is received () via a wireless communication channel, which signal requests initiation of pre-cycle warm-up for one or more components of an internal combustion engine. It is determined () whether at least one of the one or more components requires pre-cycle warm-up. When at least one of the one or more engine components requires pre-cycle warm-up, the at least one of the one or more components is warmed up ().

Apparatus and method for pre-cycle warm-up via wireless communication

A valve lifter guide () includes a base () and at least one conduit () extending from the base (). The conduit () has a first inwardly curved surface () opposed to a second inwardly curved surface () such that the conduit is capable of holding a valve lifter () between the first inwardly curved surface () and the second inwardly curved surface ().

When it is desired to transmit important or secure information to one or more communication units, a message is transmitted (200) to only valid communication unit ID codes. The message requests an acknowledgment transmission from the communication unit, including the communication unit's ID code. When no acknowledgment is received for a particular ID code, the message is transmitted again after a period of time (204). When only one acknowledgment is received for a particular ID code, the important or secure information is then transmitted (206) to that particular ID code. When more than one acknowledgment is received for a particular ID code, no important or secure information is transmitted to that particular ID code, and the ID code is flagged (207) as a potential unauthorized ID code.

Method of transmitting security codes to communication units

An identification (ID) code (204) in a memory slot (203) within a communication unit (200) is programmable only through a received RF message and a valid trigger for programming the memory slot (203). No other connection to the radio, such as a standard programming port (206), is capable of being used to program the memory slot (203). An ID code (204), such as a security ID, is programmed via an RF message. The ID code (204) is a special code known to a communication system. No request for a communication resource is granted to a communication unit (200) that does not have the ID code (204), thereby keeping unauthorized users from gaining access to the communication system.

Method of programming a radio identification code in a communication unit

A method for detecting unauthorized use of a communication unit (102) in a secure wireless communication system includes monitoring (201) a wireless communication channel (103) presently supporting a secure communication. It is determined (202) whether the secure communication is encrypted with active system encryption parameters. When the secure communication is not encrypted with the active system encryption parameters, a communication unit (102) involved in the secure communication is indicated (203) as a potential unauthorized communication unit (102). The steps of monitoring, determining, and indicating are performed by a communication unit (102) or a central controller (101).

Method of detecting unauthorized use of a wireless communication channel

A method for detecting unauthorized use of a communication unit in a secure wireless communication system includes receiving, by a central controller, a service request from the communication unit via the wireless communication system. The central controller determines whether the service request is requesting an unencrypted communication resource or an encrypted communication resource. When the service request is requesting an unencrypted communication resource, the central controller determines whether the service request substantially matches a historical utilization pattern. When the service request does not substantially match the historical utilization pattern, the central controller indicates that the communication unit is a potential unauthorized communication unit.
