Patent ID: 7630204

Claim:
A system comprising: a) an electronic device having electronic circuitry and a housing; b) a device holder having first and second states, wherein: i) said electronic device is reversibly attachable with said device holder; ii) said device holder is retained in said first state when attached with said electronic device; iii) detachment of said electronic device from said device holder is operative to cause said device holder to adopt said second state; and iv) at least one of a first size relation, a second size relation and a third size relation between a first rectangular prism and a second rectangular prism is true, wherein said rectangular prisms are defined as follows: A) said first rectangular prism minimally circumscribing the combination of said electronic device and said device holder in said first state while said device is attached to said electronic device, B) said second rectangular prism minimally circumscribing said device holder in said second state and wherein said size relations are defined as follows: I) according to said first size relation, a ratio between a longest dimension of said second rectangular prism and a longest dimension of said first rectangular prism is at least a first value that is at least 1.5; and II) according to said second size relation, a ratio between a product of the two longer dimensions of said second rectangular prism and a product of the two longer dimensions of said first rectangular prism is at least a second value that is at least 1.5, and a ratio between a second longest dimension of said second rectangular prism and a longest dimension of said second rectangular prism is at least a third value that is at least 0.3; and III) according to said third size relation, a ratio between a volume of said second rectangular prism and a volume of said first rectangular prism is at least a fourth value that is at least 1.5, and a ratio between a shortest dimension of said second rectangular prism and a longest dimension of said second rectangular prism is at least a fifth value that is at least 0.3.
