Abstract
Abstract An alerting device for a selective call receiver (100) efficiently generates a tactile vibration alert and an audible alert simultaneously. A vibrator motor (15) includes a modified eccentric weight (14) which becomes an efficient air mover upon being rotated about the axis (13). Integral to the eccentric weight (14) is a sound producing orifice (28). The orifice (28) generates an audible alert in response to air moving either across or through the orifice (28). The audible alert can be selectively enabled by the selective call receiver user, or by the message type received.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
An alerting device enclosed in a housing, for use in vibrating a communication device having a decoder for generating an alert signal in response to detecting received information, said alerting device comprising: means for rotating a shaft about a first axis of rotation, the means for rotating being responsive to the alert signal for rotating said shaft; an eccentric weight coupled to said shaft and capable of being rotated about said first axis to generate tactile vibration in the housing; and said eccentric weight coupled to an orifice for generating an audible alert by air movement produced in response to said eccentric weight being rotated about said first axis.
Claim 2
Dependent Claim
109 words
An alerting device enclosed in a housing, for use in vibrating a communication device having a decoder for generating an alert signal in response to detecting received information, said alerting device comprising: means for rotating a shaft about a first axis of rotation, the means for rotating being responsive to the alert signal for rotating said shaft; an eccentric weight coupled to said shaft and capable of being rotated about said first axis to generate tactile vibration in the housing; and said eccentric weight coupled to an orifice for generating an audible alert by air movement produced in response to said eccentric weight being rotated about said first axis.
Claim 3
Dependent Claim
15 words
The alerting device of claim 1, wherein said orifice is adjacent to said eccentric weight.
Claim 4
Dependent Claim
110 words
A communication receiver enclosed within and coupled to a housing, said communication receiver including: a receiver for receiving information; decoding means responsive to received information for generating an alert signal in response thereof; means for rotating a shaft about a first axis of rotation, the means for rotating being responsive to said alert signal for rotating said shaft; an eccentric weight coupled to said shaft and capable of being rotated about said first axis to generate tactile vibration of the housing; and said eccentric weight coupled to an orifice for generating an audible alert by air movement produced in response to said eccentric weight being rotated about said first axis.
Claim 5
Dependent Claim
110 words
A communication receiver enclosed within and coupled to a housing, said communication receiver including: a receiver for receiving information; decoding means responsive to received information for generating an alert signal in response thereof; means for rotating a shaft about a first axis of rotation, the means for rotating being responsive to said alert signal for rotating said shaft; an eccentric weight coupled to said shaft and capable of being rotated about said first axis to generate tactile vibration of the housing; and said eccentric weight coupled to an orifice for generating an audible alert by air movement produced in response to said eccentric weight being rotated about said first axis.
Claim 6
Dependent Claim
15 words
The communication receiver of claim 3, wherein said orifice is adjacent to said eccentric weight.
Claim 7
Independent Claim
98 words
A method of producing a tactile and audible alert in a communication receiver, the communication receiver having a decoding means for generating an alert signal in response to detecting received information, said method includes the steps of: (a) rotating an eccentric weight about an axis at a first rate in response to the alert signal; (b) generating a tactile alert upon rotating the eccentric weight; and (c) generating an audible alert at an orifice coupled to the eccentric weight by air movement produced in response to the eccentric weight being rotated about the axis at the first rate.
Claim 8
Independent Claim
98 words
A method of producing a tactile and audible alert in a communication receiver, the communication receiver having a decoding means for generating an alert signal in response to detecting received information, said method includes the steps of: (a) rotating an eccentric weight about an axis at a first rate in response to the alert signal; (b) generating a tactile alert upon rotating the eccentric weight; and (c) generating an audible alert at an orifice coupled to the eccentric weight by air movement produced in response to the eccentric weight being rotated about the axis at the first rate.
