#Ski Binding Release Value Calculator

Calculates the initial indicator value (z-value) according to ISO 11088 standard.

Installation

Add to your Gemfile: gem ski_binding_calculator, run $ bundle install.

Even though not version 1.x this gem is stable and fully tested. Productive use is possible but at your own risk.

The gem is not version 1.x because some features are missing. According to ISO 11088 there are beside the indicator release value also twist and forward lean tolerances. Those are missing and will be implemented one day.

Usage

You can give the calculator a hash with the following key value pairs:

key	value
weight	float, string
height	float, string
sole_length	float, string
birthday_year	int, string
birthday_month	int, string
birthday_day	int, string
type	string

A key can be a string or symbol.

Measuring Units & Formats

The measuring units and formats of the attributes are as follows:

attribute	unit
weight	[kg]
height	[cm]
sole_length	[mm]
birthday_year	[yyyy]
birthday_month	[mm]
birthday_day	[dd]
type	["Type1-", "Type1", "Type2", "Type3", "Type3+"]

Example

Regarding the last two sections a hash could look like that:

{ :type => "Type2", 
  :weight => "70", 
  :height => "170", 
  :sole_length => "315", 
  :birthday_year => "1983", 
  :birthday_month => "01", 
  :birthday_day => "01" }

Codes

In ISO 11088 table B.1 are codes defined. We map the codes to digits as follows:

code	digit
A	0
B	1
C	2
D	3
E	4
F	5
G	6
H	7
I	8
J	9
K	10
L	11
M	12
N	13
O	14
P	15

The mappings allow us to use the codes as array indexes in the yaml files.
